Hello,

I'm confused on how the postback works in website and web application because,

I have a button and in that I have given a sleep time for about 30 seconds and in another page on the same time when I try to do any activities like, click redirect etc.

In Web application the above scenario works without any issue.

In Web Site till the button event comes out the sleep time all the other activities will be hang up.

Please explain me on this.

Thanks in advance.
