host header

class myIPRelations {

 

"192.168.30.119 images.test.com"

 

}

 

 

when HTTP_REQUEST {

 

set newHost [findclass [IP::remote_addr] $::myIPRelations " "]

 

if { [string length $newHost] > 1 } {

 

HTTP::header replace Host $newHost

 

}

 

}

 

 

 

The above rule does not seem to work.

 

When we go threw the bigip we see the following result when we run a tcp dump from the server.

 

 

GET /parts/img/bcl/bc23220.jpg HTTP/1.1

 

 

Host: images.test.com

Now when we go to the server directly it works- this is what we see.

 

this is from a tcpdump on the server again. Notice we do not see the "referer" in the capture above

 

 

GET /parts/img/acd/10072.jpg HTTP/1.1
