Modifying HTTP Version

We have just implemented a F5 based solution and have encountered a problem where SSL based transactions via a proxy just hung. Tracked down to IE 6 (HTTPM settings) HTTP version 1.0, something odd in the combination of proprietary web server, squid proxy and the F5.

 

 

Difficult to fix as we cannot control the state of IE 6 on customer PCs and cannot modify the proprietary web server.

 

 

I have managed to get around it with an iRule in the F5 as follows:

 

 

Any incoming HTTP 1.0 GET set the HTTP version to 1.1.

 

Any outgoing HTTP 1.1 set the HTTP version to 1.0.

 

 

It works but I am concerned about the following:

 

 

The following iRule snippet re-writes the HTTP version in the GET passed to the web server BUT also deletes any other data (language, cookie, etc).

 

 

if { [HTTP::version] eq "1.0" }

 

{

 

HTTP::cookie "1.1"

 

}

 

On out going traffic I do the reverse, set the HTTP version to 1.0.

 

 

The question/s are:

 

Is does this also modify the data from the web server????

 

 

As we are using cookie persistence (insert method) do I clobber the "inserted" cookie and lose persistence???

 

 

On input can I modify the HTTP version without losing the remainder of the data????

 

 

Any help appreciated, Ian
