How many ways to rewrite http request and response for hostname, port and URI rewrite

The Stream profile is used to re-write Links in a webpage. For example if you masked the backend URL from the client - You might have links that point to backend URL

The good news is that the good folks at F5 had written something to around it

Here is a link that may help

Let us know if this works?

Hi The Bhattman

Thanks for reply. This IRULE seems horrible :) but again the same question the below three methods would be used in which condition for my scenario described earlier.

A)- Use stream profile in virtual server configuration B- Use stream IRULE C- Use Redirect Rewrite in http profile

Hi Ghost-rider,

Yes the iRule looks very complicated, but it does work for many people. In your case it could be overkill.

So with the streams are tyring to re-write links on a webpage or hide them from the URL on the internet browser?

it's been a while someone answered this. But I had a similar situation and below iRule worked great

when RULE_INIT { 

     Set the hostname that the client makes request to (do not include protocol)  
    set ::external_hostname "external.com"  

     Set the hostname that the BIG-IP will rewrite requests to  
    set ::internal_hostname "server1.local.intra:8445"  

     Log debug messages to /var/log/ltm? 1=yes, 0=no.  
    set ::proxy_site_debug 0  
 }  
 when HTTP_REQUEST { 

    if {$::proxy_site_debug}{log local0. "Received request from [IP::client_addr] -> [HTTP::host][HTTP::uri]"}  

    if {$::proxy_site_debug}{log local0. "Rewriting [IP::client_addr]'s Host header to $::internal_hostname"}  

     Rewrite the Host header   
    HTTP::header replace "Host" $::internal_hostname  

 }  
 when HTTP_RESPONSE {  

     Check if the status indicates a redirect  
    if {[HTTP::is_redirect]} {  

       if {$::proxy_site_debug}{log local0. "Rewriting [IP::client_addr]'s redirect"}  
          Rewrite the Location header replacing the internal hostname with the external hostname  
       HTTP::header replace Location [string map -nocase {$::internal_hostname $::external_hostname} [HTTP::header Location]]  
    }  
 }
