some headers and cache questions
Posted: Wed Jan 23, 2008 2:21 am
I need to check the etag of a webpage everytime, so that I can check did the user has visitor the page. However, I have some information will need to pass in by url variables, and there is a problem now. Once the url vars are different, (pixel.php?a=1/pixel.php?a=2/.....) the browser will think that they are actually different file, and will not request with "If-None-Match" header, is there anyway to tell the broswer that they are actualy the same?
Thanks~
