Bad Request - Invalid Hostname Iis7
is IIS? (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.

Can you leverage more info –Medet Tleukabiluly Jan 29 '15 at 4:27 add a comment| up vote 22 down vote FWIW, if you'd like to just allow requests directed to any hostname/ip then you can set your binding like so:

Call us at (85LaingFebruary 17, 20091 0 0 0 In this scenario, HTTP requests were being sent from a non-Windows machine and https://blogs.msdn.microsoft.com/webtopics/2009/02/17/http-400-bad-request-when-client-sends-invalid-httphost-header-value/ were being responded to with a “Bad Request – Invalid Hostname” error by http://solvedcomputer.blogspot.com/2012/09/http-400-bad-request-invalid-hostname.html 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: bad request [time+date] [clientip+port] [serverip+port] HTTP/1.0 POST /vdir/page.asp 400 - Hostname – The 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 bad request - 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 =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

And i have surf a lot on the web to find the solution but all the stuff i found from the Googling was just messy crap. After playing with IIS settings and changing some configuration, finally i have found the solution for HTTP 400 - Bad Request (Invalid Hostname) Error. Actually In my IIS i don't know why but 'Default Web Site' virtual directory was not there, and after completion of setup for my web application it was crashed instead of starting smoothly. - When you get a message like this Turn off friendly HTTP error messages in IE. 1. To do this go to Tools >> Internet Options >> Advanced. 2. Uncheck show friendly HTTP error messages. 3. Once you have done this you should get a more detailed message which will point you to the real problem. Steps to Solve HTTP 400 - Bad Request (Invalid Hostname) Error Bad Request: Your browser sent a request that this server could not understand. Step 1. First open your inetmgr (internet manager) and look for the "Default Web Site", if it's not there you can create it (Using virtual directory path as c:\Inetpub\wwwroot). It will help you to deploy your application under that. Note: By default the Web applications installing under the "Default Web Site" are using PORT 80.It means you can access your web application by just typing the virtual directory name(Ex: http://localhost/Vir_Dir). But if you are installing your application under separate website then you must have to use another port in order to run it, because "Default Web Site" sites are using Port 80 by default (So in case of separate website you need to access it like: http://localhost/Vir_Dir:81 or any other port number) - So now we are clear that we can run a single website on Port 80 at a time. If you will try to start two websites on a single port, it will throw a below given error. Step 2. Right click on the virtual directory and select Properties. Step 3. Now in Web Site Tab make IP address value as (All Unassigned) Step 4. Click on Advanced... button given near the IP Address field (Refer above screen shot) and then on Advanced Web Site Identification Window select default IP address and click on Edit... button. - Now Here is the key thing, you need do is Blank the Host Header Value.Means there should not be any value in host header value text box. - Now just click Ok button and click Apply and Ok, and try to browse the application now..... :) SHAIKH KABIR Email ThisBlogThis!Share to TwitterShar
