(inetmgr.exe) It may not be registered to accept all hostnames on 8080. For example, if you set it up for mysite.com:8080 and hit it at localhost:8080, IIS will get the request but not have a hostname binding to match so it rejects. Outside of that, you should check the IIS logs (C:\inetpub\logs\wmsvc#) on the server and see if you are seeing your request. Then you'll know if its a problem on your client or on the server itself. share|improve this answer answered Jan 28 '11 at 17:59 Taylor Bird 5,6481628 bah.

Intellect ConnectHome / Intellect Connect / How do I Fix a "Bad Request (Invalid Hostname)" Error on http://stackoverflow.com/questions/4831097/bad-request-invalid-hostname-iis7 a Webpage using IIS? Technical problem with your Windows Hosting? Let our Microsoft Certified experts handle the problem for you. Chat Now How do I Fix a "Bad Request (Invalid Hostname)" Error on a Webpage using IIS? Typically when a web site is displaying the follow error it means that the site is not listening on the correct http://www.serverintellect.com/support/iis/fix-bad-request-invalid-hostname/ IP or the host headers are missing. Bad Request (Invalid Hostname) To access the host headers and address issues for a site follow these steps. Start by logging into the web server where the site is hosted. Now open up IIS Manager. Expand the web sites folder to display all of the sites in the right hand frame. Now right click on the domain name and select "Properties". The default tab is the Web Site tab, click the Advanced button next to the IP address. This will display all the host headers for the site. Click the "add" button to add a host header to the site. In this example we are going to add a www host header since it is missing. Now select the same IP address as the domain is running on enter port 80 and input the www version of the domain name. Click Ok three times and the host header should be successfully added. Having Problems with Windows Server? Try our troubleshooting service Microsoft
LaingFebruary 17, 20091 Share 0 0 In this scenario, HTTP requests were being sent from a non-Windows machine and were being responded to with a “Bad https://blogs.msdn.microsoft.com/webtopics/2009/02/17/http-400-bad-request-when-client-sends-invalid-httphost-header-value/ Request – Invalid Hostname” error by the IIS server. Beginning in IIS 6.0, “Bad Request” errors are almost always returned by HTTP.sys, so the next step was to look in the httperr.log file for further evidence of the failure condition. There was an associated log entry that corresponded to the error message the user saw: [time+date] [clientip+port] [serverip+port] HTTP/1.0 POST /vdir/page.asp 400 - Hostname – The bad request problem was easily reproducible, so a network trace was captured of the client’s HTTP request and the server’s response. The network trace showed that the client was sending invalid data in its HTTP:Host header field. Here is what the client’s request looked like: 10:57:56.424 001C0F71134B 005056B5682F HTTP POST Request from Client HTTP: POST Request from Client HTTP: Request Method =POST HTTP: Uniform Resource Identifier =/vdir/page.asp bad request - HTTP: Protocol Version =HTTP/1.0 HTTP: Accept = text/html HTTP: User-Agent =e.RPG HTTP: Host =http://ip_address/vdir HTTP: Content-Length =664 The problem here is that the HTTP:Host header contained forward slashes. After the client was configured to not send http:// nor /vdir in the Host header, the HTTP requests were successful. The valid HTTP requests now looked like this: 10:59:21.400 001C0F71134B 005056B5682F HTTP POST Request from Client HTTP: POST Request from Client HTTP: Request Method =POST HTTP: Uniform Resource Identifier =/vdir/page.asp HTTP: Protocol Version =HTTP/1.0 HTTP: Accept = text/html HTTP: User-Agent =e.RPG HTTP: Host =ip_address HTTP: Content-Length =664
