Remove port number from URL

Hello Viversectors,

You have two options :

1) The proper manner is to do it from the backend servers by modifying absolute links by relative links:

Relative links looks like /toto/tata

Absolute links are similar to

2) If you cannot change it or ask for that, you can modify your irule to modify also the domain.com:80 by domain.com and the Location header if contains http://

when HTTP_REQUEST {
 STREAM::disable 

 if { [HTTP::header exists "Accept-Encoding"] } {
    HTTP::header remove "Accept-Encoding" 
 }

 if { [HTTP::header exists "Location"] } {
    set Location [HTTP::header Location]
    if { $Location contains "http://"} {
       HTTP::header replace Location [string map {"http://" "https://"} [HTTP::header Location]]
    }
 }

}

when HTTP_RESPONSE {

if {[HTTP::header value Content-Type] contains "text" || [HTTP::header value Content-Type] contains "xml"  } {
  Replace http:// with https:// and domain.com:80 by domain.com 
 STREAM::expression [list {@http://@https://@} {@domain.com:80@domain.com@}]
  Enable the stream filter for this response only
 STREAM::enable
 }

}

I think with this irule you will cover all your need.

Waiting for your update.

Regards
