Simple Reverse Proxy with iRules

Hi, I know u said u want to make this using iRule -  but I recommend you do it with policies. L7 policies use much less CPU than iRules and are easier to administer. 

You create a virtual server and add a tcp and http profile - no other profiles needed. than you create a new pool with the node you need. than you create a new policy and in there, create a new rule with the conditions:

When:

"http host is any of f5wiki.pva.sozvers.at at request

Then:

Replace http host with value "mediawiki.pva.sozvers.at" at request

Forward traffic to pool "your pool" at request

Your failure with the iRule is the "http::redirect" . this sends a response to the client with the redirect to the new DNS name. this is wrong. If u want to do this with iRule:

when HTTP_REQUEST {

if { [HTTP::host] eq "f5wiki.pva.sozvers.at"} {

HTTP::header replace "f5wiki.pva.sozvers.at" "mediawiki.pva.sozvers.at"

      pool /Common/yourpoolname

    }
