Re: adding a parameter to a URL

[Marcus Kool <marcus.kool@xxxxxxxxxxxxxxx>]

Shaine,

Because you use the 302: prefix the URL that you pass back from the redirector
to Squid is sent back to the browser and because of the 302 the browser
sends a new request to Squid and the new URL is the URL that the redirector sent
in the first place.  This URL is passed by Squid to the redirector and now you
have an endless loop.

solution:
- do not use the 302: prefix, or
- modify your perl code so that it checks for "orchard=66677722" in which case it must not 
rewrite the URL.
