Parsing request using iRules : trying to find the equivalent of scriptname

Hi,

Yes I've had a good look at the HTTP::path option, but the problem is that it will take say a url of

http://www.TSite.com/art/gallery.cgi/mammals?animal=dog&color=black

and make it

/art/gallery.cgi/mammals

I need to extract just up to the filename... however many directories that might be... e.g. want this

/art/gallery.cgi

So in other words what makes it tricky is that we have other stuff after the filename, but before the querystring component.

But it's looking like it isn't very easy... with the apache rewrite utility, I think this was the equivalent of asking for the scriptname.

Thanks,

Toni
