The URLs of my projects in WAMP are not resolving as I\'d expect. For example, I\'d expect the project in the folder c:\\wamp\\www\\project1 to have the URL http://project1/
Your wamp seems to be configured to run a website on the normally non-existant domain helloworld.
add:
127.0.0.1 helloworld
inside this file: c:\windows\system32\drivers\etc\hosts
Make sure you start your text editor with administrator privileges to be able to edit that file.
This will tell your computer that the otherwise non-existant domain helloworld should be resolved to your loop back address.
