Bad Request - Invalid Hostname IIS7

FWIW, if you'd like to just allow requests directed to any hostname/ip then you can set your binding like so:

<binding protocol="http" bindingInformation="*:80:*" />

I use this binding so that I can load a VM with IE6 and then debug my application.

EDIT: While using IIS Express to debug, the default location for this option's config file is

C:\Users\{User}\Documents\IISExpress\config\applicationhost.config

This page by Microsoft describes how to set up access to IIS Server Express from other computers on the local network.

In a nutshell:

1) from a command prompt with admin privileges:

netsh http add urlacl url=http://[your ip address]:8181/ user=everyone

2) In Windows Firewall with Advanced Security, create a new inbound rule for port 8181 to allow external connections

3) In applicationhost.config, in the node for your project, add:

<binding protocol="http" bindingInformation="*:8181:[your ip address]" />

Do NOT add (as was suggested in another answer):

<binding protocol="http" bindingInformation="*:8181:*" />

The above wildcard binding broke my access from http://192.168.1.6:8181/

Did you check the binding 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.
