IE/Opera + Dev Server = slow, problematic

[Kaan Soral]

I can't use IE or Opera for testing with development server (local).

• For some reason some of the scripts/images don't load. For the ones that load, it takes a huge amount of time for them to load compared to Firefox/Chrome.
  
• When you make a request, it takes some time for it to show up on the logs. (IE is much much worse than opera)

Do you have similar experiences?

I have seen this before and I believe it is due to the browser making multiple parallel connections to the dev server. The dev server only supports a single connection at once so some/many of these connections will time out or just fail. It is worse if you have multiple browsers making requests against the same dev server.

I have had OK results when accessing the dev server by IP rather than localhost. To try this you need to start the dev server with the argument --address 0.0.0.0 and then you can access it using the IP address of the machine the dev server is running on. Hopefully that helps.

For docs on the dev server command line arguments see here:

Correction: The necessary argument is --address=0.0.0.0

Thanks for the suggestion Bryce

I just had this idea now, If there is any http headers or modifications that will prohibit IE/Opera from making async requests we may try those. (Make responses HTTP 1.0 etc.) It should be a not so hard modification on maybe dev_appserver.py or other files that prepare the response
Any ideas?

Weirdly it runs fine in IE Tester (all versions), which has been my solution for now.

The App Engine team is currently working on a new development server
that has a multi-threaded frontend and supports concurrent requests.

The announcement is here:
https://groups.google.com/d/topic/google-appengine/TCQuJpF44cY/discussion

And you can get the code from the Google Code project:

Cheers,
Brian
