We have recently encountered several bugs in the old connect / express version we are using:

• error reporting recursion when setting headers after they are sent -- worked around in ParsoidService

• URL decoding breakage as in http://parsoid-lb.eqiad.wikimedia.org/zhwiki/Alcohol_120%

We should consider upgrading either to a newer express version, or use another similar framework like restify.

Things to consider / ensure:

• form data handling needs to support both urlencoded and multipart/form-data, and should not create temporary files
• need continued support for gzip encoding etc
• would be nice to have consistent JSON-based error reporting built in, but could also be implemented as a logging backend (although that might not handle errors in the framework)
