Re: [squid-users] url_rewrite_program

that error isn't my primary issue at this point, although i guess i do
need to look in my script more careful, my main issue and i really
hope someone here can help me out with this is following:

as i said i've got special URL that i need to send certain URLs and
that URL will do whatever it needs to do and then send it back to
original URL, so that user gets to his/her destination as expected,
now i think when i get that URL sent to url_program_rewrite it does
rewrite and since that URL sends user back to original URL and that
URL is in my squid config set for rewrite, squid goes into loop
here...

anyone can help me resolve this issue? i'd highly appreciate that..

thanks
