Change Host Value

All,

 

 

I am trying to do something I thought would be pretty simple but I am missing something... whenever I see a request for www.outsidedomain.com I need to change that to servername. When I see the response I need to flip it the other way. Here is what I tried but maybe I am going about this the wrong way.

 

 

when HTTP_REQUEST {

 

if { [HTTP::host] equals "www.outsidedomain.com" }{

 

HTTP::header replace host "servername"

 

log local0. "The header is [HTTP::header host] "

 

log local0. "The Host Value is [HTTP::host]"

 

} else {

 

log local0. "No Changes Made"

 

}

 

}

 

 

The HTTP::host entry in the log is the same as when it came in but the HTTP::header host is the value I set. I understand that I need a when HTTP_RESPONSE for the return traffic but I can't even get this first part to work. What am I doing wrong? Thanks.
