CirrusOverwrite Response Headers with existing pool selection irule
I have an application that direct's traffic to a one of 2 pools and the irule works perfectly
when HTTP_REQUEST { switch -glob [string tolower [HTTP::uri]] { "/ac" { pool V249.48-P31202 } "/client" { pool V249.48-P31203 } } }
Now they are having a problem as they are getting a 302 from the server for one URL and they want to overwrite the respone header as follows:
Change from Location: http://xyz.abc.com:31202/ac-fedmgr/affwebservices/public/saml2sso?SPID=AITTAC To https://xyz.abc.com/ac-fedmgr/affwebservices/public/saml2sso?SPID=AITTAC
I have no idea on how to add this to the existing IRULE if any one is out there please advise.

If you're just looking to replace the redirect URL, add this to your existing iRule (modify as required):
when HTTP_RESPONSE { if { [HTTP::header exists Location] } { HTTP::header replace Location [string map {"http://xyz.abc.com:31202" "https://xyz.abc.com"} [HTTP::header Location]] } }If the response event sees a Location header, present in a redirect, it will perform a string replacement of the offending URL.

the problem is that it is coming in on the save virtual server.....as the irule is applied.
isn't it correct? ssoiextrafedqatmp.ext.ampf.com is resolved to the virtual server ip, isn't it?

If you're caught in a redirect loop, there's a very good chance that the application is causing this because it doesn't like what the client is asking for. Sometimes this is a specific URI value, but more often than not I find its a Host header. Give this a shot: add the following to the top of your HTTP_REQUEST event.
HTTP::header replace Host "ssoiextrafedqatmp.ext.ampf.com:31202"Otherwise, take a closer look at what it's actually redirecting you to.
