Re: back button loses cart

texte = Ken:On a related note: I'm another person who's had IE weirdness. I've done this already: adding [random] x 3 tags to links and no caching headers to the page. But that hasn't stopped caching totally when using the back button. The back button is the bugger: Since it's navigation without a link involved, so I can't specify the random tags and thus uniqueness, and the browser merely backs up to page.tpl&aa=654, with 654 being an example of the result from the 3 random tags. It pulls this page from cache and shows the raw webdna tags in place without data. I presume this is because it's showing the page out of cache and it's not being interpreted via Webcat. My workaround has been to expressly request users to use my link (with the random tags) to back up. But that doesn't help if their credit card fails the webcat validation test and gets kicked back as not accepted (the we don't accept that card error page generation). The user then has to use the backbutton out of the error page and voila...gets the raw webdna tags.So far I've only seen this with Mac IE 4.5.1 (not tested 5). Not seen it with navigator or Win IE (but that doesn't mean the latter doesn't play naughty intermittently).I'd love to know a solution to this. When raw tags appear it really throws off the user.Thanks,Reg HarrisElegantly put by Kenneth Grome:> >The fact of the matter is this: > >If the browser is caching pages it shouldn't cache, the best webdna >method for preventing caching is to add a unique value to your URLs. >This absolutely prevents improper caching by browsers like IE, and >it's been discussed dozens of times on this talk list.------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
