JAGGRAB Protocol

The JAGGRAB protocol is used to 'grab' cache files from the file server and download them.

It is a text protocol, similar to HTTP, and the client will fall back to HTTP if JAGGRAB is unavailable. This generally happens in unsigned mode.

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

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.
