# What is Ajax IM?

Ajax IM ("Ajax Instant Messenger") is a browser-centric instant messaging framework.

|

## What is Ajax IM?
|
||||
|
||||
It uses AJAX to create a real-time (or near real-time) IM environment that can be used in conjunction with existing community and commercial software, or simply as a stand-alone product.

Node Server Memcached Protocol
|
||||
for logging users in and out of the server.
|
||||
-------------------------------------------
|
||||
|
||||
add <username> <!ignore flags> <!ignore exptime> <bytes> [!ignore noreply]\r\n
|
||||
|
||||
- <username> is the username of the new user
|
||||
|
||||
- <flags> and <exptime> are ignored.
|
||||
|
||||
- <bytes> is the number of bytes in the data block to follow, *not*
|
||||
including the delimiting \r\n. <bytes> may *not* be zero.
|
||||
|
||||
After this line, the client sends the JSON-encoded data block:
|
||||
|
||||
<data block>\r\n
|
||||
|
||||
- <data block> is JSON-encoded information about the user, having a length
|
||||
of <bytes> bytes.
|
||||
|
||||
After sending the command line and the data block, the client awaits
|
||||
the reply, which may be:
|
||||
|
||||
- "STORED\r\n", to indicate that the user is or has been logged in.
|
||||
|
||||
- "NOT_STORED\r\n", to indicate that there was a problem storing the
|
||||
new user data.
|
||||
|
||||
Retrieval command:
|
||||
------------------
|
||||
|
||||
The retrieval commands "get" and "gets" operates like this:
|
||||
|
||||
get <type/identifier>\r\n
|
||||
gets <type/identifier> <type/identifier> <...>\r\n
|
||||
|
||||
- <type/identifier> is one of:
|
||||
- session/<session_id> where <session_id> is the session of an
|
||||
existing user.
|
||||
> returns information about the user
|
||||
- username/<username> where <username> is the (properly formatted)
|
||||
username of a logged in user.
|
||||
> returns information about the user
|
||||
- list/
|
||||
> returns a list of all online users
|
||||
- online/
|
||||
> returns an integer value of the online user count
|
||||
|
||||
After this command, the client expects zero or more items, each of
|
||||
which is received as a text line followed by a data block. After all
|
||||
the items have been transmitted, the server sends the string
|
||||
|
||||
"END\r\n"
|
||||
|
||||
to indicate the end of response.
|
||||
|
||||
Each item sent by the server looks like this:
|
||||
|
||||
VALUE <key> <flags> <bytes>\r\n
|
||||
<data block>\r\n
|
||||
|
||||
- <key> is the key for the item being sent
|
||||
|
||||
- <flags> is set to 0
|
||||
|
||||
- <bytes> is the length of the data block to follow, *not* including
|
||||
its delimiting \r\n
|
||||
|
||||
- <data block> is the data for this response, usually in JSON format (exception: online/).
|
||||
|
||||
If some of the keys appearing in a retrieval request are not sent back
|
||||
by the server in the item list this means that the server does not
|
||||
hold items with such keys (because they were never stored, or stored
|
||||
but deleted to make space for more items, or expired, or explicitly
|
||||
deleted by a client).
|
||||
|
||||
Logging out
|
||||
--------
|
||||
|
||||
The command "delete" allows for explicit logging out of users:
|
||||
|
||||
delete <username>\r\n
|
||||
|
||||
- <username> is the username of the user the client wishes the server
|
||||
to log out.
|
||||
|
||||
The response line to this command can be one of:
|
||||
|
||||
- "DELETED\r\n" to indicate success
|
||||
|
||||
- "NOT_FOUND\r\n" to indicate that the user with this username was not
|
||||
found.
