I want to download the actual source of the webpage.
Flesk really has the answer on this one (+1).
Another straight-forward way to debug HTTP connections is Netcat, which is basically a powerful telnet utility.
So let's say you want to debug what's going on in your HTTP request:
That will send the request header to the server (you'll need to press the enter key twice to send).
After that, the server will respond:
So the server returns 302, which is the HTTP status code for redirect and thereby prompts the "browser" to open the URL passed in the Location-header.
Netcat is a great tool to debug and trace all kinds of network communication and helped me a lot when I wanted to dig a little deeper into the HTTP protocol.
The reason it fails is because http://www.windowsphone.com attempts to set a cookie, which is checked on https://login.live.com which creates another cookie and redirects back to windowsphone.com if successful.
You should look into http://docs.python.org/library/cookielib.html
If you want to use curl, allow it to create a cookie-file like so:
Run
more myCookieJarin your shell and you'll see something like this:Run (notice the -b option before 'myCookieJar'):
and you'll get the contents of the page in the file windowsphone.html as you see it in your browser.
