rewriting location header from server

Hi everybody,

 

 

I have an application on which my client connect to F5 on https and the F5 decrypt to server. The problem is my server (in response) is sending to F5 for each request an301 redirect and so the F5 is not able to analyze it: For example I did a curl on server with the host:

 

curl -v x.x.x.x -H https://toto.net

 

* About to connect() to x.x.x.x port 80

 

* Trying x.x.x.x ... connected

 

* Connected to x.x.x.x ( x.x.x.x ) port 80

> User-Agent: curl/7.15.5 (i686-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5

< HTTP/1.1 301 Redirection

 

< Server: WEB-Access-Server/1.9

< Location: http://toto/index.htm

 

< Connection: Keep-Alive

 

Error 301

 

 

 

 

HTTP Error 301

 

301 Redirection

 

 

Vous allez être redirigé vers

 

 

Contactez l'administrateur du serveur si ce problème persiste.

 

 

 

* Connection 0 to host x.x.x.x left intact

 

* Closing connection 0

 

 

 

As you can see there is a 301 redirect with a different Location.

 

I tried to change this irules:

 

when HTTP_RESPONSE {

 

if { [HTTP::is_redirect] } {

 

STREAM::expression {@http://@https://@}

 

STREAM::enable

 

}

 

}

 

 

Thks for your help,

 

 

 

B./

    Hi Bertrand,

     

     

    You can use a custom HTTP profile with rewrite redirects enabled to have TMM rewrite the redirect to https://.

    Also, the stream profile only affects payloads. If you wanted to do this rewrite in an iRule, you'd want to use HTTP::header:
