Suppress IE HTTP Error Pages

I'm trying to send custom error-pages with the HTTP-Server I wrote. No

when it comes to the IE (6 in my tests), the browser replaces the error

pages I send with it's own. And in this case destroying the website

layout I use.

How can I assure that my custom error pages will be used?

I'm sending for example:

[code]

HTTP/1.0 404 Not Found

Connection: close

Date: the actual date

Server: myHTTP Server v.0.0.1

Content-Type: text/html

Content-length: 4711

<!DOCTYPTE..........

[/code]

and so on...
