Nimbostratusirule for HTTP header rewrite
Hi,
Fairly new to F5's (as you can probably tell from the question) but I wish to write an irule which will:-
replace http://10.10.10.10/whatever1/whatever2.txt
with http://www.test.co.uk/whatever1/whatever2.txt
and forward the connection on to two internal servers. Our belief is that the internal servers need to see the connection arrive with the name and not the IP address!
This purely an intranet solution.
One solution is that we would change this at the source of the connection, but most client users would attempt to connect via IP address.
Any kind person able to offer what a possible irule would like like? Apologies if this is discussed elsewhere...
Thanks,

Hi Jas,
Welcome to DC. You can start with an iRule like this to replace the Host header in requests before they're sent to the pool:when HTTP_REQUEST { HTTP::header replace Host "www.example.com" }
If the servers each have a unique host header they're looking for, you can use an iRule and datagroup like this:

That did it.

Hi all,
I'm wondering if the above iRule will replace the HTTP header in the client side or just replace the http header and forward it to the internal server(s).

it will just replace the header sent to the server. - If you're looking to perform an actual client side redirect, wherein the client sees the new host address, you'll want to use the HTTP::redirect command.
