== Gnutella Web Cache ==
Copyright © 2002-2009 Shareaza Development Team.  --[[User:Ocexyz|Ocexyz]] 23:27, 27 July 2009 (UTC)}}
A '''Gnutella Web Cache''' (often referred to as '''GWC''') is a web service that gives computers connecting to [[Gnutella2|G2]], [[gnutella]] or similar [[P2P network]]s IPs to connect to if they do connect for the first time or do not know IPs to connect to for some other reason. This means GWCs (and similar services) are essential for the initial network connection. However, UHCs (on gnutella) and UKHLs (on G2) are more and more taking over the services once performed by GWCs.


==Gnutella Web Cache==
== How you can help ==
If you have a dedicated server and can spare some extra bandwidth then please consider running a GWC. People that don't have a dedicated server or are on normal broadband consumer lines should not run a cache from home.

Gnutella requires Gnutella Web Caches (GWC) to get IPs to establish a connection to the network. These are critical to ensuring the health of the network. If you have a dedicated server and can spare some extra bandwidth then please consider running a GWC. People that don't have a dedicated server or are on normal broadband consumer lines should not run a cache from home.

* '''Get String Breakdown:'''
** Update a leaf
*** "?update=1&ip=(ip):(port)&x_leaves=(leaf count)
** Ping Variable
*** Appends &ping=1 to identify the cache name in debug messages (for gnutella and gnutella2 in 2.4.0.0, but only for gnutella2 now in 2.4.0.X for spec1 cache compatibility).
*** This feature new to Shareaza.
** Network Variable
*** Appends &net=gnutella2 on Gnutella2 queries.
*** Does NOT append a network variable on Gnutella(1) queries.
** Client Name / Version Format (2.4.0.0 and earlier):
*** &client=(Shareaza 4 letter code (RAZA / RAZB) )
*** &version=(Shareaza's version)
** Client Name / Version Format (2.4.0.X):
*** If Gnutella
**** &client=(Shareaza 4 letter code (RAZA / RAZB) )
**** &version=(Shareaza's version)
*** If Gnutella2
**** &client=(Shareaza 4 letter code (RAZA / RAZB) )+(Shareaza's version)
 
* '''GWC Response Matching:'''
** i|
*** Informational output alone will not be taken as GWC 'success.'
** i|access|period|(time in sec.)

** i|update|period|(time in sec.)
*** Time in seconds before Shareaza is allowed to update to the cache.
** i|force|remove and i|update|warning|bad url
*** Remove the GWC from the internal list.

*** Similar to the 'spec' parameter, except that it does not force, instead it simply negotiates the specification.
* Special Data Requests
** info
*** Outputs extra details of your cache.
**** Start with the informational response: I|
***** Ex: I|open-source|1
** support
*** Outputs USEFUL details of your cache.
**** Start with the informational response: I|
***** Ex: I|support|gnutella2
** getnetworks
*** Outputs the enabled networks in two formats.
**** Start with the informational response: I|
***** For the 'I|nets|' line
****** The third field contains the supported networks joined by '-'.
***** For the 'I|networks|' line
****** Interpret the fields from 3 and beyond as individual network names to challenge against.
**** Examples
*****
****** I|net|gnutella-gnutella2
****** I|networks|gnutella|gnutella2
* Update Extension Variables:
** x_leaves
*** Number of leaves running on a given hub or ultrapeer.
*** '''Value must not be greater than an integer value of 2047.'''
** x_max
*** Maximum number of leaves possible on a given hub or ultrapeer.
*** '''Value must not be greater than an integer value of 2047.'''
** uptime
*** Value submitted must be an integer value of the number of seconds of uptime.
*** '''Value must not be greater than an integer value of 1 year (31536000) and less than 1 hour (60).'''
 
=== Pinging Caches With Your Cache ===
* '''Please follow this standard:'''
** '''Client: TEST'''
** '''Version: Your Cache's Name'''
*** The old value for "version" was 1
* '''Some variables to attach to the ping (compatibility):'''
** '''multi'''
*** Used by some gwcs in their pings to other gwcs.
*** <nowiki>It tells the pinged cache to ignore the "net" parameter (so it should never say network not supported) and outputting the pong using this format, if possible, "I|pong|[cache name] [cache version]|[supported networks list]|[url adding is enabled]" - example: I|pong|Skulls 0.2.8a|gnutella-gnutella2|1 </nowiki>
*** Used by Skulls GWC only.
** '''cache'''
*** This is added to every request made by some gwcs, it is for statistical purposes only.
*** It simply tells the remote cache that the client is a GWC.
* '''Help'''
** For PHP
*** Use the fsockopen() function to open a connection to a cache.
**** Make sure you "write" to the fsockopen carry value to open the GWC's target file.
***** [http://us.php.net/manual/en/function.fsockopen.php http://us.php.net/manual/en/function.fsockopen.php]
 
=== Variable Combination Standards ===
* '''Net variable decides specification!'''
** There are many ways to determine spec., but going with net is the safe way.
** Skulls GWC does not use the network parameter to determine specification level.
** Beacon Cache (I and II) uses the network parameter to determine the specification level.
* '''Your cache needs to be able to process certain combinations of variables.'''
** Update variable
*** Update should not fail if absent if spec. 2.
**** A Specification 2 parameter.
* Spec 1 parameters used in Spec 2:
** Should still accept hostfile and urlfile responses for spec. 2.
*** Beacon Cache (I and II) accepts these parameters on spec 2.
* The 'spec' paameter can be used to force a specification:
** Only known to exist in Beacon Cache II, it can force the request to be handled as a specification 1 or 2 request.
** Spec 1 = 'spec=1'
** Spec 2 = 'spec=2'
** If 'spec' is not equal to any current spec, then default to the predetermined spec.
* '''Multiple variable requests'''
** If for instance a ping and request exist, you should always handle them properly.
*** Same goes with other combos like an update and ping, statfile + ping and info.
** Handle multiple variables as BEST as possible!
*** Some scanners and GWCs like to fit all their requests into one URL send.

===Gnutella Web Cache===
Gnutella requires Gnutella Web Caches (GWC) to get IPs to establish a connection to the network.  These are critical to ensuring the health of the network.  If you have a dedicated server and can spare some extra bandwidth then please consider running a GWC.  People that don't have a dedicated server or are on normal broadband consumer lines should not run a cache from home.
 
A GWC is a simple script that can be put on any webserver that supports one of the following scripting languages:
*JSP (Java Servlet)
**[http://web.archive.org/web/20061108091447/http://www.mager.org/GWebCache/ Java Servlet GWebCache Application (Archive.org)]

                      # The vendor code with version number is in the 6th field.
    * Request Control Variables:
          o getleaves
                + Used to obtain leaf counts of hubs given
                + 4th field ultilized for current leaf count.
                + 7th field ultilized for maximum leaf slots possible.
                + Use this as 'getleaves=1' or 'getleaves' to enable.
          o getclusters
                + Enables/Disables clustering.
                + Use this as 'getclusters=1'.
                + Using 'getclusters' or 'getclusters=0' disables cluster output.
          o getvendors
                + Used to obtain the vendor code w/ version number of the hubs given.
                + Found in the 5th field.
                + Use this as 'getvendors=1' or 'getvendors' to enable.
          o getuptime
                + Used to obtain the vendor code w/ version number of the hubs given.
                + Value is static, do not change the value given when time passes.
                + Found in the 6th field.
                + Use this as 'getuptime=1' or 'getuptime' to enable.
          o spec
                + To force the specification parameter
                + Currently is only supported by Beacon Cache II
          o pv
                + Similar to the 'spec' parameter, except that it does not force, instead it simply negotiates the specification.
    * Special Data Requests
          o info
                + Outputs extra details of your cache.
                      # Start with the informational response: I|
                            * Ex: I|open-source|1
          o support
                + Outputs USEFUL details of your cache.
                      # Start with the informational response: I|
                            * Ex: I|support|gnutella2
          o getnetworks
                + Outputs the enabled networks in two formats.
                      # Start with the informational response: I|
                            * For the 'I|nets|' line
                                  o The third field contains the supported networks joined by '-'.
                            * For the 'I|networks|' line
                                  o Interpret the fields from 3 and beyond as individual network names to challenge against.
                      # Examples
                            *
                                  o I|net|gnutella-gnutella2
                                  o I|networks|gnutella|gnutella2
    * Update Extension Variables:
          o x_leaves
                + Number of leaves running on a given hub or ultrapeer.
                + Value must not be greater than an integer value of 2047.
          o x_max
                + Maximum number of leaves possible on a given hub or ultrapeer.
                + Value must not be greater than an integer value of 2047.
          o uptime
                + Value submitted must be an integer value of the number of seconds of uptime.
                + Value must not be greater than an integer value of 1 year (31536000) and less than 1 hour (60).
 
Pinging Caches With Your Cache
 
    * Please follow this standard:
          o Client: TEST
          o Version: Your Cache's Name
                + The old value for "version" was 1
    * Some variables to attach to the ping (compatibility):
          o multi
                + Used by some gwcs in their pings to other gwcs.
                + It tells the pinged cache to ignore the "net" parameter (so it should never say network not supported) and outputting the pong using this format, if possible, "I|pong|[cache name] [cache version]|[supported networks list]|[url adding is enabled]" - example: I|pong|Skulls 0.2.8a|gnutella-gnutella2|1
                + Used by Skulls GWC only.
          o cache
                + This is added to every request made by some gwcs, it is for statistical purposes only.
                + It simply tells the remote cache that the client is a GWC.
    * Help
          o For PHP
                + Use the fsockopen() function to open a connection to a cache.
                      # Make sure you "write" to the fsockopen carry value to open the GWC's target file.
                            * http://us.php.net/manual/en/function.fsockopen.php
 
Variable Combination Standards
 
    * Net variable decides specification!
          o There are many ways to determine spec., but going with net is the safe way.
          o Skulls GWC does not use the network parameter to determine specification level.
          o Beacon Cache (I and II) uses the network parameter to determine the specification level.
    * Your cache needs to be able to process certain combinations of variables.
          o Update variable
                + Update should not fail if absent if spec. 2.
                      # A Specification 2 parameter.
    * Spec 1 parameters used in Spec 2:
          o Should still accept hostfile and urlfile responses for spec. 2.
                + Beacon Cache (I and II) accepts these parameters on spec 2.
    * The 'spec' paameter can be used to force a specification:
          o Only known to exist in Beacon Cache II, it can force the request to be handled as a specification 1 or 2 request.
          o Spec 1 = 'spec=1'
          o Spec 2 = 'spec=2'
          o If 'spec' is not equal to any current spec, then default to the predetermined spec.
    * Multiple variable requests
          o If for instance a ping and request exist, you should always handle them properly.
                + Same goes with other combos like an update and ping, statfile + ping and info.
          o Handle multiple variables as BEST as possible!
                + Some scanners and GWCs like to fit all their requests into one URL send.

===Gnutella Web Cache===
Gnutella requires Gnutella Web Caches (GWC) to get IPs to establish a connection to the network.  These are critical to ensuring the health of the network.  If you have a dedicated server and can spare some extra bandwidth then please consider running a GWC.  People that don't have a dedicated server or are on normal broadband consumer lines should not run a cache from home.
 
A GWC is a simple script that can be put on any webserver that supports one of the following scripting languages:

Gnutella Web Cache

A Gnutella Web Cache (often referred to as GWC) is a web service that gives computers connecting to G2, gnutella or similar P2P networks IPs to connect to if they do connect for the first time or do not know IPs to connect to for some other reason. This means GWCs (and similar services) are essential for the initial network connection. However, UHCs (on gnutella) and UKHLs (on G2) are more and more taking over the services once performed by GWCs.

How you can help

If you have a dedicated server and can spare some extra bandwidth then please consider running a GWC. People that don't have a dedicated server or are on normal broadband consumer lines should not run a cache from home.
