User:Old Death/Gnutella Web Cache

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A Gnutella web cache, also known as a GWebCache, is used by Gnutella2 and Gnutella clients to make an initial connection to their respective networks. A GWebCache uses standard HTTP to transmit data.

Gnutella Web Cache[edit]

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.

A GWC is a simple script that can be put on any webserver that supports one of the following scripting languages:

^ multi-net: This should be set to Yes only if the cache can handle multiple networks simultaneously without erroneously mixing data of various networks; many caches support multiple networks but they can be used only on ONE network, that it is set in the settings.

      • spec:
        • To force the specification parameter

Pinging Caches With Your Cache[edit]

  • 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.
      • 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.
    • 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

Variable Combination Standards[edit]

  • 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.
