Packet Information


Message ID:0x24
  
Message Name:SID_READCOOKIE
  
Message Status:DEFUNCT
  
Direction:Client -> Server (Sent)
  
Used By:Starcraft Shareware, Starcraft Broodwar, Diablo Shareware, Warcraft II, Starcraft, Starcraft Japanese, Diablo
  
Format:(DWORD) First DWORD from S -> C
(DWORD) Second DWORD from S -> C
(STRING) Registry key name
(STRING) Registry key value
  
Remarks:Much like a website cookie, simply stores some arbitrary string to a 'cookie jar' to save preferences et al. which can be retrieved later by the server.

Not used because it was quickly discovered that storing preferences produces less problems and were faster by storing them server-side, associating them with the account. It is somewhat curious that these packet IDs are close to SID_PROFILE/SID_WRITEPROFILE (0x26 & 0x27).

Found at: battle!190216FBh and battle!1901D660h, respectively.

It's not defunct, Battle.Net clients still support it. So it can be used with Battle.Net emulators, or if someone uses man in the middle.
