Why do I get crashes or strange output when updating my sites with     WebDAV?  5. Why do I get a 15-second delay before a file is uploaded when     updating my sites with WebDAV?1. Why not use mirror, rsync, fmirror etc etc?sitecopy is for maintaining web sites via FTP. This cannot be donewith rsync or fmirror, which require shell accounts on the web server.You can use mirror instead of sitecopy - the basic functionality isduplicated. But, sitecopy does NOT go to the FTP server and see what'sthere every time - this is the fundamental difference between sitecopyand mirror. This saves bandwidth, and startup time. sitecopy also hassome features missing in mirror (though the reverse is also true),such as remote file move and interactive confirmations.sitecopy can use WebDAV as well as FTP - this brings all theadvantages of WebDAV to site maintenance (better security, speed etc).See <http://www.webdav.org/> for more information about WebDAV.2. What is WebDAV?See the FAQ sheet at:http://www.webdav.org/other/faq.html3. Should I use WebDAV or FTP?From sitecopy's perspective, you should take into account thefollowing points:- Given correct server configuration, DAV is faster than FTP andhas more secure authentication mechanisms.- Currently, you cannot set the file permissions of remote filesusing DAV. This can be done with FTP. This might be important toyou if you use CGI scripts.See the WebDAV FAQ for more comparison of WebDAV vs FTP.4. Why do I get crashes or strange output when updating my sites withWebDAV?Is the server running Apache 1.3.6 or before? There is a known bugwith these releases which can be worked around in sitecopy by adding   http noexpectto the entry in the rcfile. If possible, you should upgrade tothe Apache 1.3.9 (or later), which has fixed this bug. Those usingApache 1.3.9 (or later), do not need to use 'http noexpect'.5. Why do I get a 15-second delay before a file is uploaded whenupdating my sites with WebDAV?This is the same problem as above - use 'http noexpect' in yourrcfile entry.
