Problem: Opening a Office document with WebDAV from a browser. (Download, edit, upload is too elaborate) The solutions I consider: 1. Using Internet Explorer: <STYLE> A {behavior: url(#default#AnchorClick);} </STYLE> <A href = "http://localhost:9080/a/documents/4 folder = "http://localhost:9080/a/documents/4" target = "_top"> Open in Web Folder View </A> (Thanks to Juergen Plasser) You can't open the document directly, but you can open the folder and then open the document with wedav. Drawback: Only works with IE. Users of other browsers or operating systems need to download, edit, upload. 2. Install a small http or xml-rpc server on each client. All clients need to have the same port number. Then you could linkt to: http://localhost:9999/?document. The server at localhosts opens the document using COM. Benefit: This works with any browser. Drawback: You need to install the server at each client. 3. Use Samba on Unix as a wrapper. Drawback: You need a unix server Benefit: Even Offices without webdav support can access to documents. (The link would be <a href="file:///Z:/...") 4. Use WebDrive or TeamDrive (about 40$ per client) I think I will use solution 1. What do you think?
