Hostname turns into server internal name

If you open developer tools in the browser do you see a 302 redirect? If you do, what is the value for Location?

Sounds like a redirect by the internal server. You can configure redirect rewrites to take care of that

The problem is we don’t know if the server returns the external name in redirect only or in all http response links.

The best solution is to look at the server configuration if you can set the external url. Most of http server support it and it will increase f5 performances instead of irule inspecting all response pages.

Create a HTTP profile, enable Redirect Rewrites to All.

Hi All,

Thanks for you replies. I suspect from the internal server doing this redirection but i do not know exact reason.

I will check more detail and inform you.

Hi Kevin by the way, there is a redirection irule on VIP like ;

if [HTTP::uri] equals "/" do HTTP::redirect "/blabla"

Regards,

If you're unsure what's being sent back from the backend, run a tcpdump from the command line, and capture to a file (-w option), grabbing the full packet (-s 0 == don't truncate the snap) and then peruse the response either via tcpdump, or if you're more desktop orientated using something like wireshark

Often seeing exactly what is coming back can be a good hint as to why it's doing that

Hi,

Here is the full description ;

We have 2 VIPs, first one is http VIP and used for only https redirection works ok. Second one is https and SSL offlading comes here. Also, there is a irule on https VIP to redirect another path comes from client which works ok too ;

when HTTP_REQUEST { if { [HTTP::path] equals "/" } { HTTP::redirect "/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html" } }

This is the Client, F5 and Server connection ;

Client <-----> F5 (HTTPS, Redirect IRule) <-----> Server (HTTP, 8000)

By the way, this is SAP application.
