Questions tagged [webob]

Any questions regarding WebOb and its usage in Python WSGI applications.

WebOb is a Python library that provides wrappers around the WSGI request environment, and an object to help create WSGI responses. The objects map much of the specified behavior of HTTP, including header parsing, content negotiation and correct handling of conditional and range requests.

This helps you create rich applications and valid middleware without knowing all the complexities of WSGI and HTTP.
