How to avoid cache in asp.net iframe page

[tanyali]

Hi,

I am using asp.net and c#
i have an iframe within a page PageA.
the source file for the ifram is page PageB.

I type in some text and press search from PageA, the result will be displayed in the iframe.
The problem is when I search for the same text string a second time, the result come out straightaway without executing the search action, which is because of the cache.
I want to avoid the cache in the page.
I tried to add code to the parent page PageA
<meta http-equiv="pragma" content="no-cache" />
in the aspx page, and
Response.Cache. SetCacheability (HttpCacheabili ty.NoCache);
in the aspx.cs page
and neither works.

Any ideas ?

Thanks,

Tanya

What you appear to want to achieve is a postback every time the page searches. Are you using ispostback? Here is a related post, suggest searching the site:
