[[Category Cache]]

|
|
|
== Introduction ==
|
|
|
|
The JAGGRAB protocol is used to 'grab' cache files from the file server and download them.
|
|
|
|
It is a text-based protocol, similar to HTTP/0.9, and the client will fall back to HTTP if JAGGRAB is unavailable. This generally happens in unsigned mode and helps users who are behind firewalls.
|
|
|
|
== Request format ==
|
|
|
|
A request is simply the text JAGGRAB, a space, the path to the file and a newline character. Therefore, it is very similar to a HTTP/0.9 GET request.
|
|
|
|
JAGGRAB /path/to/file
|
|
|
|
=== New engine ===
|
|
|
|
In (perhaps all) new engine clients, the client prefixes the JAGGRAB request line with a single byte (value 17).
|
|
|
|
== Response format ==
|
|
|
|
The response is simply the raw file data. Once the response is sent, the connection is closed.
|
|
|
|
== Files ==
|
|
|
|
There are a number of files which map to files in the cache.
|
|
|
|
* '''/crc''' - the CRC table
|
|
* '''/title''' - cache 0, file 1
|
|
* '''/config''' - cache 0, file 2
|
|
* '''/interface''' - cache 0, file 3
|
|
* '''/media''' - cache 0, file 4
|
|
* '''/versionlist''' - cache 0, file 5
|
|
* '''/textures''' - cache 0, file 6
|
|
* '''/wordenc''' - cache 0, file 7
|
|
* '''/sounds''' - cache 0, file 8
|
|
|
|
NOTE: the client will usually postfix these with random numbers, so when checking for the file only the start of the string should be examined: not the whole one. This is to help avoid caches when these files are fetched over HTTP.<BR>

NOTE: The crc is postfixed with the client revision |
