View HTTP Headers in IE
ieHTTPHeaders is an explorer bar for Internet Explorer that will show you the HTTP Headers IE are sending and receiving.
Mozilla has had a similar extension for a while now, but this link may be useful for those of you who have not yet switched from IE to Firefox.



The only thing I hate about these toolbars/Firefox extensions it’s the fact they eat extra processing speed when browsing the sites, so you may also try xheaders.com :-) I just finished it.
