NimbostratusPersistence based on Querystring
Howdy, we would like to persist based on a querystring. However, there would be two sources (clients) with the same querystring.
For example:
1. client one sends a request with a unique Querystring with name SessionID.
2. subsequent requests need to persist to the same responding web server.
3. client two sends the same querystring (SessionID) to finalise the transaction; therefore it needs to be sent to the same web server responded to above requests.
Is this technically feasible?
If not, the other option is to add the Querystring in the HTTP HEADERS but when it comes to step 3 (client two), it will send the SessionID as a querystring and we can't change this as this is a third party app.
Any assistance is appreciated.

Hi,
You can parse the query string parameter value and use it to persist off of. Will clients always send the parameter in each request? If so, here's an example to get started with:when HTTP_REQUEST { Check if query string parameter named SessionID has a value http://devcentral.f5.com/wiki/default.aspx/iRules/uri__query set sid [URI::query "?&[HTTP::query] &SessionID] if {$sid ne ""}{ Persist off of the session ID value persist uie $sid } }

Triggerman_1128Hi Aaron,
Thanks for the reply. Unfortunately, the querystring is not always in the URI.
