The problem is if you have used Arduino Ethernet Shield, then you know that you can connect a IP, But if the IP has multiple virtual hosts, it will only connect to default virtual host.

Gist is use of HTTP protocol which allows you to define host in your request on virtual host server. Here are the possible headers.

You should also provide basic debugging info like “User-Agent” etc.

Customizing Command Prompt

Working with command prompt on windows is messy. Working with multiple version of a language/compiler on windows is a trip to hell.

Possible workarounds are:

  • Set all the paths and add tags in names of binaries
    (stupid. You would have to remember all names or you will have to use some naming convention; still you will keep guessing).
  • Create users and set different versions in each user’s paths
    (Foolish. Then changing version will be like logging as different user).
  • Use a Customized Command Prompt
    (Elegant. Developers friendly)

How to Customize Command Prompt.

Create a file Called YOURSYSTEM-VER-cofig.bat. Where YOURSYSTEM is the name of the system you are using and VER is the version of that specific system like python-2.6-config.bat.
Now put some codes in the file. Like:

Then create a new shortcut Right click on empty space or File -> New -> Shortcut.

Create new shortcut
Create new shortcut

Then type %COMPSPEC% /K "C:pathtoyourfile" in it

Creating shortcut

Then Rename the shortcut to a proper name.

Rename shorcut to a Proper name
Rename shorcut to a Proper name

Then click on Finish. Now Right click on the shortcut.
