http headers in flask not working on linux server

Question

I am using Flask to generate REST API.

I want to check authorization header which is sent by mobile apps.

I am using below code

from flask import request
cookie_data = request.headers.get('auth_token')

It is working on local machine, but when i host it on server it is not working, when i debug it gives null value. The difference is, on my local machine flask version = 0.10.1 python =2.7.8 on server flask = 0.10.1, python= 2.6.9

I doubt the Python version is the issue; it probably has something to do with server configuration. Specifically, "auth_token" is not a standard HTTP header, so your server may be filtering it out from the request before it gets to Flask.

You may want to test with one of the standard headers, such as "Authorization". If this works, then it's likely that the problem is the nonstandard header.

Thanks a ton. This answer helped me after a whole day of hair pulling frustration, just because one of my HTTP Headers was user_id :)

Turns out that only alphanumeric characters or '-' are allowed.

Any headers not conforming these will be ignored.
