To clarify things:
In my first post I should have specified that I am not using an Apache server but my WordPress blog is running on Windows II6 server. My observation in my first post is true. It will only gzip the index page but not any internal pages. There are many compression tools to check.
Also I got an email from you, Frederick (on Dec. 28, 2010) stating:
“Right now, W3TC cannot control compression and headers and a few other things on IIS. Sorry. You will have to enable those options manually.”

FYI: I already enabled HTTP compression for the blog on the server.
Thanks,

UPDATE: PROBLEM SOLVED
I found the solution to this problem. Now IE8 behaves the same like the other browsers. The fix lies in WordPress core code.

Go to: “wp-includes/functions.php”
Change “$defaults = array( ‘response’ => 500 );”
To “$defaults = array( ‘response’ => 200 );”

Hi,

1. I have switched to the default theme, and tried other themes too.
The problem, described in my first post, is still there.

2. I disabled all plugins I have (I only have 8 plugins), and the problem still there.

This is really interesting with IE8: if you leave any of the required
fields blank, and even if you fill out an invalid e-mail, and click
SUBMIT. So IE8 instead of displaying the appropriate error message as coded in wp-comments-post.php, it displays an HTTP 500 Error.
All other browsers behave as expected.

Any other ideas? If you use IE8 on my posts, do you get the same result when you submit a comment with empty fields?

Thank you.
