I think this has been covered elsewhere in this forum, but the short answer is no, you cannot bypass the upstream proxies by using your own. This is because your proxy will use port 80 (like any browser) to talk to web sites and so it will get redirected as well.
Regarding your problematic site, is it possible to do Ctrl-Refresh (for IE) as shown in Robin Walker's cablemodem help pages?

Also you could enter your problematic web page into the Cacheability Engine to see if it's actually cacheable.

The HTTP headers that are usually used to gauge content freshness are:
Expires, Cache-Control, Last-Modified
If the headers indicate that the content is old, then it won't get its freshness verified as often as new content.
