Question

I have a simple website with two pages which the first page has a button and redirects to the second page.

In the second page when I press the back button the page_Load of the first page runs again instead of reading from cache.

But in IE and Chrome when I press back button the page_load is not run again and read the page from cache.

I tested it in Firefox 7 and Firefox 15.
what’s wrong?

Answer 1

I found the solution. I had an image with Src="" and it caused twice running Page_Load and running Page_Load when I Pressed back button on browser just In firefox.
according to this link firefox substitute scr="" with page Url but IE substitute it with /null.
