I have had this issue with one or two pages and can't figure it out. For example, if you go to http://www.complianceonline.com/ecommerce/control/trainingFocus?product_ id=702317&channel=M-New_JU13_Mark_JN04_DM and then click the "Buy Now" button it takes you to a screen with your shopping cart. Users accessing the site via the proxy are unable to click continue on this shopping cart screen. I can access it fine directly. I have told squid to ignore these sites but it doesn't seem to matter. Below is the only thing I can find in the log in relation to this site. Any ideas? I am running squid on a Ubuntu box.
