F5 irule for reverse proxy with rewrite

I want to get data from website and display as a different url. The node and pool commands don't help because they seem to only work by IP, while I need to pass the hostname with subdomain to get the...

HTTP::header replace Host http://docs.remotesite.com

 

i think this one should not have http://

 

e.g.

 

HTTP::header replace Host "docs.remotesite.com"

 

My uri displayed in the browser stays at /templates/docs. I would like it to change to /templates/docs/index.html

 

you need HTTP::redirect to change url in browser.

 

HTTP::redirect

 

https://devcentral.f5.com/wiki/iRules.HTTP__redirect.ashx

 

It does seem to be pulling content from docs.remotesite.com but there are some javascript files from that page that are not being downloaded "GET" correctly.

 

in your irule, it does change host header, uri and send traffic to pool_docs pool only when uri is /templates/docs or /templates/docs/. does the javascript also need to?

    So there is no way to grab content from another server and rewrite the clients URL without redirect? Similar to the Apache or 'nginx' commands, rewrite and proxy_pass ?

    no, i think it is possible. what you need to do is to rewrite request and response properly. proxypass codeshare is one of examples. ProxyPass v10/v11 https://devcentral.f5.com/s/articles/proxypass-v10-v11

    I am running version BIG-IP 11.5.2 Build 0.0.141 Final When I copy and paste the ProxyPass code into my iRule and try to save I get an error, 01070151:3: Rule [/Common/rt18877] error: /Common/rt18877:1: error: [undefined procedure: @][@] If I remove the '@' from the beginning of the code, it will save the iRule, but I don't see any Proxy Pass activity while tailing logs.

    Got Proxy Pass working with removing the '@' from the code.

    Where in the iRule snippet can I place code to rewrite the client url path seen in their browser? I tried at the end of the HTTP_REQUEST event and somewhere in the middle of that same event.
