hello, Ravikanth:

thank you so much for your help, could you tell me how to
reload/refresh the page every time.

I use:
using System.Web.Caching;
and add:
Response.Cache.SetCacheability(HttpCacheability.NoCache);
in the override protected void OnInit(EventArgs e).

and I try to add:
Respones.Expires=-1; in the Page_Load();

but the problem still exist, I have to relogin and show
the new image???

Sincerely,

haiwen

Hello Haiwen,

In order to prohibit a page from caching just place following Meta tag in the head of the html.
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

Did I answer your question?

hello, yanhong:

It still doesn't work, on the computer explorer I can make
sure the image file change immediately, but on my
application, it still keep the old image. I have to logout
the application and login in again then I can show the new
image file.

could you or anyone else help me to figure it out?

Thanks a lot,

haiwen
