Radius and HTTP Header insertion

Hi,   hard question: I have just to understand if it can be done with BIGIP and iRules.   What I need is to add a specific HTTP header to all the HTTP sessions coming from a specific IP address;...
application delivery
dev
devops
iRules

Hi Colin, and thank you for helping.

 

I will receive Radius "Start Accounting" and "Stop Accounting" data; this data contains a telephone number, and I will have to associate this telno with IP address. When I will receive HTTP sessions from that IP address, I will then have to insert an HTTP header with the 'linked' telno in the HTTP session.

 

telno = 13 digits, ipaddr = 12 digits, so let's say 30 bytes of data per radius session, considering some overhead. So with only 1MB of memory I would be able to have 30k sessions stored.

 

If this is possible, the other question is if global variables can be arrays or something like that, and if concurrent sessions of iRules can read/write to the same variable. Or, perhaps, if it would be possible to have one different variable per IP address.

 

 

Thanks again,

 

Pietro
