I do not have the >means to test this out at the moment. indeed! it reduce traffic by 20% mod_expire by apache2 is sending both exprires and cache-control:max-age=xx i cannot use ExtraHeaders, so i modify the source to add max-age, not expires still have effect on ie browser(more than 90% of the user)
yes! i can't use ExtraHeaders! why? with status "Not Modified" mathopd is NOT sending ExtraHeaders this make IE send request again and again, get NO cache-control header :( the status bar showing "downloading xx images" is "flashing" each time i click the link to another page not even make traffic high, but make user seeing the images so slow the same problem happened in apache2 with mod_header which don't add header for "Not Modified" tooo Xuefer [EMAIL PROTECTED] 2004-10-25
