Maybe I'm misinterpreting the URI spec, but it looks like even a comma
gets encoded so instead of receiving a request to /a/
before_comma,after_comma you get a request to /a/before_comma
%2Cafter_comma. I am really confused.

Thanks a lot for clarification.
While I believe this is incorrect from the perspective of the URI
spec, but it is definitely not specific to GAE.

http://docs.python.org/library/urlparse.html says that anything after
a semicolon will be considered a "parameter" and located in
request.params and not request.path .

Even so, the App Engine drops it.
And according to RFC3986 my understanding is that the semicolon can be
part of the URL (I'll not reproduce the EBNF here as it is quite
complex).

";" is not a valid char in url, you need encode it.
>>> from urllib import quote
