Client connection table in TCL

Hi,

 

 

I have come across a number of scenarious where we have developed an iRule that works with a single client (proof of concept) but then the next stage is to implement multiple client support.

 

 

This would mean creating a client "connection table" and performing all of the expected house keeping tasks required to maintain such a table, such as adding entries/deleting entries/expiring entries and making sure the table does not grow too large.

 

 

One example is where we save the client Ip, client port and a system generated integer in a table, and use this to match outbound connections from the servers.

 

 

I have given this some thought, and before i go ahead and try to do this in TCL, i wanted to see if anyone has tackled this problem before. I cant help but think that I would be reinventing the wheel, especially as we already do a lot of this stuff in LTM).

 

 

What would be great is that if we took the object oriented approach, and created a "container" which you could store entires in and retrieve data from without having to worry about the background housekeeping tasks. These could be handled as a "global" setting, i.e entry timeouts etc. This could then be re-used whenever we have this requirement in the future.

 

 

Has anyone done anything like this?

 

 

Regards,

 

Evan.
