Answer 1

can't be plainer. URL was bad. what's the question?

Answer 2

I've not seen that with a browser. But the following will get error 400 from Apache:

$telnet www.example.com 80

GET / HTTP/3.4

GET foo HTTP/1.0

others get 501 not supported, e.g.

GOO /



Normally if you ask a browser for http://www.example.com/foo it does

GET /foo HTTP/1.1 and gets a 404. IE automatically inserts the "/".



I guess you might get 400 from an active script on a webserver, where the programmer has decided to send 400 rather than the default 500-series error, or maybe trying to do WebDAV to a non-WebDAV server. But it's not normal. 400 is supposed to mean the client made an error, while 500 is if the server made an error (an active script failed, for instance). As if there was a bug in Internet Explorer (or a web proxy) causing it to generate an illegal request, not just one the server didn't understand.

Answer 3

Web sites can contain sub domains subpages so although the information associated with the web site is correct he sub address doesn't make sense hence bad request it can connect to the server and the site but the site has given a bad response IE no page wrong document etc.
