Can you explain why?
Thank you.

• parsedUrl.pathname contains only the path (file) name ( POST /upload )
• parsedUrl.path contains the name of the path and query string for 'GET' request (POST /upload?fileId=1& ... )

What I meant is the reason you need to pass some parameters in query string (as in GET) while performing POST request. Doesn't really make sense.

For example, in api known in Russia social network vk.сom must unload file to specify parameters get =)

I see. I would say it's an optional (edge case) behavior rather than default one.
Do you care to refactor your patch to make it as optional parameter with supporting tests.

Thank you.

Now (#22) you can specify custom parameter (like path) when calling form.submit().
For example code please refer to the Readme.

Thank you.
