Discussion on `Size of a request header field exceeds server limit' error

[BradMclain]

This is easy to trigger if you have a large tree of related rest models. Werkzeug and other development environments don't seem to care about this but apache does.

We should document what to do if this is encountered by users.

We should perhaps also encourage setting the development server to the same as production server to avoid nasty surprises.

This can be resolved in a couple ways:

• Changing server setting to allow for longer headers
• Not sending up all fields in the filter (sometimes hard to do)
• Terminating large trees of data with end classes eg Author instead of User
