Also added API docs regarding header encoding, incl support for RFC 5987
for filename fields in Content-Disposition headers in multipart/form-data
parts, incl. an example of an upload request with a utf-8 encoded filename.
Solves an issue with clients encoding filenames in multipart
headers in ISO-8859-1, causing an HTTP 500 response code.
This change makes ISO-8859-1 encoded headers work, sends
a 400 Bad Request instead of 500 Internal Server Error if the
request multipart headers cannot be decoded as either UTF-8
or ISO-8859-1, defines UTF-8 content type for multipart text
fields in rebuilt body and also adds support for RFC 5987 for the
multipart file upload "filename" header component.
* make sure server_port headers are properly set in reverse proxied scenarios
* overwrite request and response classes to
* always apply reverse proxy environment changes (so far missing for tornado
context)
* strip cookie name suffixes from cookie names on requests and
* be sure to set cookie name suffixes for cookie names on responses
* include script root in path used for cookies
* some minor refactoring in octoprint.server setup routines
* removed ReverseProxied class (didn't work for tornado context)
* add unit tests for the whole reverse proxy, request and response customization
