Rodolfo, 

Have you tried including some cache control directives in
your web pages?

<META HTTP-EQUIV="cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache"> 

Full spec of cache control directives can be found here:

I don't know but i wonder if specifying a public anonymous proxy in
your browser would bypass your ISP's proxy?  Maybe the same issues exist
even if you're directing requests to an external proxy of your choice?
