Hi. How can i prevent an ISP that uses proxy from sending cached pages. I have login and logout pages that set cookies and send the user back to the page he was(whichever this was).
However with a certain ISP that uses proxy, login and logout pages seem like cached and don't behave normally. In specific, even though i have the logout page to reset the cookie and get out it doesn't do anything. The cookie is unchanged.
Is
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
a good solution?
I guess in this way all data will be requested each time the user asks for a page and no cache will be used. So there will be delays for the user.
Am i right?
Thanks
John
