mod_dav is an Apache module to provide DAV capabilities for your Apache web server. It is an Open Source module, provided under an Apache-style license.
mod_dav currently implements a Class 1 and Class 2 DAV server. This means that it provides all the basic DAV facilities for manipulating resources (files) on the target web server, along with manipulating properties on those resources. In addition, it handles the (un)locking of resources so that clients can have exclusive access to modify resources.
Please donīt use this Apache module without proper access authorization on your web server, as otherwise everybody will have write access to your server !!!
