STREAM *head scratching*

Hello,

 

 

I have a VS setup on port 443 applied to external VLAN using builtin SSL profile on clientside only, http profile (rechunk, x-forwarded), empty stream profile, SNAT pool; points to a pool of web servers on port 80 with an iRule attached as follows. Environment, VLANs, SNAT are well known and working and we are using route domains.

 

 

 

when HTTP_RESPONSE {

 

if {[HTTP::header "Content-Type"] contains "text"} {

 

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

 

STREAM::enable

 

}

 

}

 

 

 

Initial page returns with broken images and the page is full of "http://" links which should have been rewritten as "https://".

 

 

 

Any Help Appreciated!

 

 

 

Kevin

    when HTTP_REQUEST { 
  STREAM::disable 
  HTTP::header remove "Accept-Encoding" 
}

    Turns out this bit of iRule above is necessary to make all this work. However the stream profile @http://@https://@ does not. It had to be modified to @http@https@

    The following expressions have different results... host = hello

    STREAM::expression @http://@https://@ does not work

    STREAM::expression @http://hello@https://hello@ does not work

    STREAM::expression @http://\@https://\@ does work

    STREAM::expression @http://$host@https://$host@ does work

    STREAM::expression @http@https@ does work

    Can anyone explain to me why certain things work and others do not. I would like to understand the parsing that is going on here.

    Regards

    That's actually very interesting. I would think that all of those forms would work. When you say "doesn't work" do you mean that it's not replacing the strings, or returning an error of some form?
