Summary

A generic and extendable WebDAV server written in Python and based on WSGI.

Main features:

• WsgiDAV is a stand-alone WebDAV server with SSL support, that can be

installed and run as Python command line script.

• The python-pam library is needed as extra requirement if pam-login

authentication is used on Linux or OSX.

• WebDAV is a superset of HTTP, so WsgiDAV is also a performant,

multi-threaded web server with SSL support.

• WsgiDAV is also a Python library that implements the WSGI protocol and can

be run behind any WSGI compliant web server.

• WsgiDAV is implemented as a configurable stack of WSGI middleware

applications. Its open architecture allows to extend the functionality and

integrate WebDAV services into your project. Typical use cases are:

• Expose data structures as virtual, editable file systems.

• Allow online editing of MS Office documents.
