How can I avoid cache?

[Shawn]

Hi.

We have a web application that is used by several different companies. Each
company have access to a couple of hundred records which they are updating
daily. One of they companies have reported many problems since their IT
department set up a proxy server. When they click a button to save data or
insert a new record all they get is a "Page cannot be displayed"-page. If
they press back in IE and try again, they might or might not be able to
perform the desired action. In general they get the "Page cannot be
displayed" 3 or 4 times when pressing back and trying again.



I'm pretty sure that this has to do with the proxy caching web pages. Is
there something I can do so that this company's proxy server won't cache my
web pages?



Thanks,

Shawn

Have you tried using :

Cache.SetNoStore();
and
Cache.SetCacheability(HttpCacheability.NoCache);

?

I haven't tried anything yet. I've never worked with caching before. Where
would I put this code?

You can put it in the Page_Load event.

VB.NET :
Sub Page_Load(sender As Object, e As EventArgs)
Response.Cache.SetNoStore()
Response.Cache.SetCacheability(HttpCacheability.NoCache)
End Sub

C#
private void Page_Load(object sender, EventArgs e) {
Response.Cache.SetNoStore();
Response.Cache.SetCacheability(HttpCacheability.NoCache);
}
