iRule to Persist based on ASP.NET Session ID

I am trying to create an iRule that will force traffic to persist to the same server based on the ASP.NET_SessionId cookie that the application inserts. I do not want the BigIP to insert its own cook...

We were given the following iRule by F5, but it is not working correctly.

when HTTP_REQUEST {

set SessionId [HTTP::cookie ASP.NET_SessionId]

log local0. "Request SessionId is: $SessionId"

if { $SessionId != "" } { persist uie $SessionID }

}

when HTTP_RESPONSE {

set SessionId [findstr [HTTP::cookie names] "ASP.NET_SessionId" 18 24]

log local0. "Response SessionId is: $SessionId"

if { $SessionId != "" }{ persist add uie $SessionId }

}

We added this iRule to a Universal persistance profile. Now when we browse to the application, images are not being displayed. When we log into the application, we get a page cannot be displayed error.

Any ideas/suggestions would be great.

Thanks.
