Choose pool based on /uri content with cookies

Hey all.

I'm sure this is probably a pretty simple issue, but I've been all over the boards and I can't seem to get it to work. I have two sites that share a public IP Address.

I've written an iRule that picks a pool based on a flag in the URI (/fms2). The server does not include /fms2, so I use a string command to redact that part of the URI. All of that is working great, although the server doesn't reply back with pointers that include /fms2 in the URI and thusly information is getting lost. I'm trying to use a pool_cookie to get it to work, but no luck. Here's my iRule, please let me know what I"m doing wrong:

when HTTP_REQUEST {

Default to not setting a pool cookie

set pool_cookie ""

Check URI set to lower case with wildcard matching

switch -glob [string tolower [HTTP::uri]] {

"/fms2*" {

pool fms2-staging_pool

HTTP::uri [string range [HTTP::uri] [string first "/" [HTTP::uri] 1] end]

set pool_cookie fms2

HTTP::header replace Host "fms2-staging.ith.local"

}

default_pool {

Check if user has pool cookie

switch [HTTP::cookie pool_selector] {

"fms2" {

pool fms2-staging_pool

}

default {

pool fms1-test

}

}

}

}

}

when HTTP_RESPONSE {

Set a pool selector cookie if a FMS2 pool was selected in request

if {$pool_cookie ne ""}{

HTTP::cookie insert name pool_selector value $pool_cookie

}

}

Thanks very much. –Sara
