Emerging Technology Briefs, developed by O'Reilly Research, offer a single-page summary of recent developments in a technology topic that we have been following. O'Reilly Research also publishes full-length industry reports, including the 2001 P2P Networking Overview and the upcoming Web Services Report.

As many as five different pieces of exploit code for recently announced Windows 2000 vulnerabilities have been made public on security mailing lists. Windows administrators are being urged to patch their systems, because workarounds may not be enough, experts say.

WebDAV (Web-based Distributed Authoring and Versioning) extends the Hypertext Transfer Protocol (HTTP) to support asynchronous collaborative authoring on the Web.

This article discusses WebDAV, which has become an important communication protocol for the Web as an extension to HTTP 1.1. It describes what WebDAV is and how it could be useful in your client/server architecture.

Managing your uploaded files with WebCT's File Manager has always been a slow process due to the Web browser's limitation of being able to handle just one file at a time. WebDAV overcomes this limitation and makes managing your WebCT files as easy as dragging your files from one folder to another.

In the first session of the XML DevCon Fall 2000 conference, Greg Stein delivered an introduction to WebDAV, the Web Distributed Authoring and Versioning protocol. Stein is an open source developer working with WebDAV and Python -- he is the author of the mod_dav Apache DAV support, soon to be an integral part of Apache 2.0.

The protocol WebDAV (World Wide Web Distributed Authoring and Versioning) is an extension of HTTP/1.1 and defines new methods for supporting collaborative work (primarily asynchronous collaborative authoring) on the Web. The new WebDAV methods provide a good basis for building Web-based collaborative applications. In order to use the new WebDAV functionality, a client application must have direct access to the protocol methods and must be able to pass certain parameters provided by the user. Common Web browsers provide only limited support for accessing HTTP methods and no support for accessing header fields directly. This paper presents a generic approach for implementing WebDAV-based applications by extending HTML forms to provide direct access to the protocol methods (HTTP and WebDAV methods) and the header fields from within a Web browser. This approach is used to develop a simple collaborative project repository based on WebDAV.

WebDAV servers come in a wide variety. Some WebDAV servers focus on collaborative authoring and file sharing in general, while others have more specific functionality exposed through WebDAV. This article is a survey WebDAV server products and services. The www.webdav.org site hosts a more up-to-date list of products supporting WebDAV.

This article will show you how to configure webDAV support for apache on your os x box, as to enable support for storing your ical calendars so you won't have to pay for .mac services. The webdav configuration settings throughout this document were originally found in an cached webdav article at goliveheaven written by jeep hauser, which are used throughout this document to set up webdav for integration with ical. The credit for the technical underpinnings goes to him.

Software development today often takes place among multiple groups of software engineers who are geographically dispersed. A key challenge in supporting these distributed software development teams is making the software remotely accessible and editable via the Internet, addressing issues such as overwrite prevention, security, authentication, access control, and reliable operation across high-latency network connections.

There is nothing worse when setting up a website than having to build some complicated method of viewing and updating the information on the site. There are lots of solutions -- using a local copy, using a combination of HTTP and FTP tools to download the original and upload the changes and of course the full-blown dynamic/content managed system that provides that nice cuddly front end for you to enter the information into.

The Web Distributed Authoring and Versioning (WebDAV) working group of the Internet Engineering Task Force (IETF) has extended the HyperText Transfer Protocol (HTTP) to support remote collaborative authoring of network resources of any media type. This process of extending HTTP exposed several weaknesses of HTTP in the domain of collaborative authoring, notably in parameter marshalling, support for multi-resource operations, support for operating on hierarchies of resources, and status reporting. The need to have built-in locking support was also identified. This paper describes these shortcomings of HTTP, and collects this experience in the form of requirements for the next generation Web infrastructure.

Like it or not, the Web has been co-opted. Its grassroots foundations have long since been paved over by large corporations looking to assert their influence over the direction of Web standards and technology. When did the Web "jump the shark"? With the advent of banner ads? When the W3C contemplated allowing royalties on standards? (Take your pick.)

INCUBATING IN THE standards process for several years, the WebDAV (Web-based Distributed Authoring and Versioning) protocol -- designed to add interoperability and collaborative capabilities to the Internet -- has been steadily making its way into the everyday tools of business users and stands poised to transform how users interact with the Internet.

The irony was intense. The frustrating, awkward nature of collaborative authoring over the Internet became increasingly evident as draft after draft of the WebDAV Distributed Authoring Protocol specification was edited, spelling out how collaboration could be much easier, much more fluid, if leveraged on the Web's standard infrastructure. The collaboration scheme the authors used when writing the specification was typical: each draft required the author to make the revisions, then e-mail changes back to the other authors.
