Support for resumeable uploads

[Kieran P]

It seems Nginx has a big feature missing, the ability to support resumable uploads.

There are two third-party modules available at the moment, however, both have serious downfalls.

• The most popular seems to be ​https://github.com/vkholodkov/nginx-upload-module - however, it doesn't support any version above 1.3.8. And the author of the module has no plans to update.
• The other up and coming module is ​https://github.com/pgaertig/nginx-big-upload - however, there are numerous reports of incompatibilities with SPDY and the dependancy on Lua for it to run.

Thus neither of these modules is suitable for someone running Nginx 1.4+. Nginx needs a solid, supported resumable upload functionality. If not compiled by default, it should be able to compile with a flag, the same way SPDY is added when compiling.
