Server Header Checker Tool

[asha]

is a good free tool to check server header, this tool provides a great snapshot of technical issues that may be causing problems with a site. You can also find the server header checker at the same site, which provides a quick look at the server response and path happening when you enter a moved URL, or a non-existent or bad URL.
