环回127.0.0.1在Win 7中不起作用

Question

I am trying to communicate with comms from a server to a client on the same PC. So if I send the word "Hello" from one it appears on the other like a chat program. As I am on one PC I set IP to 127.0.0.1 and port to 7000 although port could be lots of other numbers. When I press to connect it will not connect to local host.

On XP laptop all is OK so something in set-up is not good. I looked at opening Firefox and typed in Local Host it works, tried 127.0.0.1 it works so IIS is working BUT that is not what I want. I looked for files with local host in and find in C:\\Windows\\System32\\drivers\\etc a file called hosts with 127.0.0.1 and IPv6 version ::1 commented out. Uncommented and still nothing works.

Switched off firewall still no good, switched off Virus detection still nothing.

What have I missed how can a chat program talk on loopback in Win7?

I'm not sure if you are intentionally typing in Local Host separately. The host "localhost" is what you are after, followed by the appropriate port number.

Example:

http://localhost:7000/url_to_chat

If you have been doing that correctly, then you just need to define two different ports for each app if you are running both on the same machine in Windows 7 and done.

If you are using Visual Studio's IIS Express (recommended as you don't have to run as an admin), all you have to do is specify the port number and create the folder. You'll then have to run each app.

Hope that helps.
