Requests hanging when using Chrome and development server (python)

[kwellman]

Hello,
I'm using Google App Engine with the Flask web framework on Ubuntu and
I've had this annoying problem with Chrome (Windows) for the past
month. When I'm testing my program by running the GAE development
server, my requests often hang and the page that I'm requesting will
never load. In order to get it working again I have to switch to the
development server process and hit Ctrl+C once or twice and then the
page will finish loading fine.

I've never had this problem with IE8 or Firefox 4, and it was working
fine with Chrome until about a month or so ago. I prefer Chrome,
especially for development, and would like to use it but this "bug"
has driven to Firefox for now.

Has anyone else experienced this problem?

Thanks.

I've noticed this as well with Chrome. No idea why it happens though.

Same here. I noticed it a few months ago with Chrome on Mac, and since then switched to Firefox for my local development. It's odd.

On a related note, I had IE 9 pushed to me in a Windows update but it
wont connect to local host at all. Any ideas?

I had this problem a while ago, and later figured a solution:

In short, in to fix it, in Chrome 12 go to Preferences/Under the Hood, and uncheck "Predict network actions to improve page load performance". This was known as "DNS prefetching" in previous Chrome versions.
