Using variables with CO= in mod_rewrite ...

[Gareth Bult <gareth@xxxxxxxxxxxxx>]

Hi,

I'd like to be able to use a variable in a cookie setting for example;

<VirtualHost *:80>
        ServerName       myserver
        RewriteEngine    On
        SetEnv             MYPATH "Hello_World"
        RewriteRule      .   - [CO=COOKIEID:%{MYPATH}:.domain.com:120]
        ProxyPass        /      http://myrealserver:8080/
</VirtualHost>

But for some reason environment variables don't seem to work.

Essentially I'd like to insert the domain name component of the request into a cookie .. does anyone know how this can be done ?

tia
Gareth.
