Proxy.pac problems

Hi All,

I'm trying to get my proxy.pac working (I copied the one from our
current NS Proxy).

I put the proxy.pac file in the squid/bin directory and added the
following line to the squid/etc/mime.conf file:

\.pac$ application/x-ns-proxy-autoconfig anthony-unknown.gif - image

I've confiugured my NS Browser (NS 4.7) to use Proxy Autoconfiguration
for the followinf address: http://ia-br.interaccess.nl:8080/proxy.pac.
When I try to load a page Squid keeps complaining with the message
below:

Expected MIME type op application/x-javascript-config or
application/x-ns-proxy-autoconfig.

Use the configuration from the previoyus session instead?

Does someone have a clue to what's going wrong? I've compared my
proxy.pac to some of the .pac's in the mailing-list archives, but I
can't find anything wrong with it (because if there is something wrong,
why doesn't Netscape complain).

Regards,

Richard van Denzel.
