Hitting the back button after previewing a change to a wiki page results in the change going away, in IE. 

 

Steps to reproduce:

1. In XWiki, through MS Internet Explorer, Click "Edit this Page" on any page

2. Add a line at the top

3. Click Preview

4. Click the browser's Back button

 

The line you added in step 2 is gone.

 

This appears to be counter to the default behaviour in IE.  I made a test page with a <textarea>, and IE doesn't whipe out the text when I go to another page, and then back.  I added the default xwiki meta header tags, thinking that might be the culprit, but that doesn't have any affect.

 

Any ideas?

 

Thanks,
