Caching problems in IE

[tshad]

How do we handle Caching in IE?

It seems that my system works fine in Mozilla and Netscape when I make
changes.

But in IE the changes are not brought across when someone has been to the
site before. If they have been here before and hit the same page, the old
page is rendered which will cause errors as things that are expected with
the new changes are not being done, such as session cookies being created or
updated.

I understand you can handle caching from the web.config, but why is IE
having a problem and Mozilla not?

Thanks,

Tom

How would I do that?

The problem is just that if I go to a page in IE and then makes some
changes - If I go to that same page, my browser will load the old version of
the page. If the old page was looking for something that is not there any
more, I would get an error. As soon as I hit the refresh button, the new
version of the page gets loaded and it works fine.

It is hard to show it - as it is dependent on you loading a page and them my
making a change that would cause it to fail if you re-ran it.

I only have that problem with IE.

make sure the IE setting for "Check for newer version of stored pages" is set
to "Automatically" , which is the default. For some bizarre reason people
sometimes change this setting to "Never" which leads to the behavior you are
describing.

Dou you do anything in your code that prevents caching?

In "Automatica lly" mode IE will check for new version of page only once per
session. For development purposes you should set "Every visit to the page"
mode.

That's fine for me.

But I don't want this happening for people that are using my site as it will
not work correctly when I make changes to my pages.

Hi, maybe i wasnt clear:
if the user has setup their browser to behave in this way (so that it will
never check for new versions of pages), then your site in fact should behave
this way. This is a very non-standard browser setup and any user with this
setting will have problems with using websites in general, including Google,
etc, not just your site.

Either set the OutputCache directive on your page(s)

<%@ OutputCache Location="None" %>

or set the Cache property of the HttpResponse in your code-behind class:

Response.Cache. SetCacheability (HttpCacheabili ty.NoCache);

(which is equivalent to the directive shown above)
