Strange different behavior

[Bernardf FRIT]

Hi,

I'm facing a pretty strange issue. URLs not supposed to be cached are in 
cache when
requested by firefox but not by lwp.

I'm suspecting cookie management... but I don't realy know how to avoid 
caching
these URLs. Any help would be apreciated.

URL like XX.html are XXX.php rewrited.

In vcl I have :

if (req.request == "GET" && req.url ~ "\.(html|php)") {
            pass;
}

And when requesting pages :

1. Under Linux/GET
