Those are great questions. The IP assignments change very frequently.
Cell phones are often connected for < 1 minute. The 'module' would
probably need to query a database for every hit to the "homepage".
These are cell phones so they don't surf very many sites and when they
do it's quite slow. It's only the 1xRTT technology. (basically 56k
speeds)

Thanks again for the feedback.

Right. And I can understand your frustration. Squid as out of the box do
not easily support this.

I had an unpublished patch for Squid-2.6 that enabled external acls to
return additional header details which would suit your problem nicely,
but it's somewhat lost in time by now I am afraid.

I guess the currently supported method is to design an ICAP server or
eCAP module doing the needed request transform.

Or alternatively resurrect that old external acl functionality. Wasn't
hard to implement (an hour including testing I think). Might make sense
to extend this to url rewriters as well.

How often do the IP assignments change?

Or most importanly, how long time needs to pass before an IP is reused
for another customer?
