GAE's http header length limit, bug or undocumented restriction?

[tempy]

Hi All,

I've hit a behavior that doesn't exist on the dev-server, which is
that custom http headers on the response seem to be limited to around
400 characters. One custom header that I'm using which is regularly
about 700 chars is simply silently dropped from the response.

Firstly - this restriction, if its not a bug, should be documented.
I've spent a whole lot of time building a feature around a big http
header which worked fine all along on the dev server, if I have to re-
architect this feature then it'll be a few days of work down the
tubes.

Secondly - is this a bug? This issue:
http://code.google.com/p/googleappengine/issues/detail?id=407
Seems to indicate that this is a bug, but its marked as fixed and it
is clearly not fixed. If it is a bug, is there a known workaround?

It would be really great if someone from google could weigh in here.
Thanks!

400 is the specification limit for http header elements.
(actually I think it is 400 characters converted to Base64)

Most things don't break if you go over this,

The max size for all Http Headers is 4k

Really? I tried to find something in the spec about header lengths and
didn't find anything. According to this thread:
http://stackoverflow.com/questions/686217/maximum-on-http-header-values
there are no maximums. And where did you get the 4k number? Thanks!

I'd have to look it up, it came up a lot at Microsoft In the IPTV group.

Hi All,

I've got the same error and i can't find any information in the documentation.

For me the limit is a little increased, is about 600 character for a single header...

Is this a bug or an unreported restriction??

Thanks to all

Fabio
