Hi, Is there a way to provide fallback URL when HTTP redirect times out? What I'm trying to achieve is that when I hit the original url, I would respond with HTTP redirect (300, 307?) giving the browser new URL and the fallback URL in case the new URL times out? I was also considering doing this client side but it just does not seem t...

Send a "304 Not Modified" for images stored in the datastore

I store user-uploaded images in the Google App Engine datastore as db.Blob, as proposed in the docs. I then serve those images on /images/<id>.jpg.

Any reason not to use USE_ETAGS with CommonMiddleware in Django?

The only reason I can think of is that calculating ETag's might be expensive. If pages change very quickly, the browser's cache is likely to be invalidated by the ETag. In that case, calculating the ETag would be a waste of time. On the other hand, a giving a 304 response when possible minimizes the amount of time spent in transmission. ...

How do I make php page return a 503 error (or anything non-200).

A former developer wrote or client-server api in PHP. It simply sends messages as xml using post/response in a very simplistic fashion.

Why would HTTP transfer via wget be faster than lftp/pget?

I'm building software that needs to do massive amounts of file transfer via both HTTP and FTP. Often times, I get faster HTTP download with a multi-connection download accelerator like axel or lftp with pget. In some cases, I've seen 2x-3x faster file transfer using something like: axel http://example.com/somefile or lftp -e 'pget -n...
