There has been some talk recently about how to time out stalled requests
after a period of time. The hooks essentially were there but a few new
features had to be added. The patch is described at

	http://db.w3.org/Library/latest.sql

I have now committed an update that does support graceful timeout of
requests.  It is possible to set/change the timeout for all requests using
these HTHost methods

	extern int HTHost_eventTimeout (void);
	extern void HTHost_setEventTimeout (int millis);

defined in

	http://www.w3.org/Library/src/HTHost.html

The default timeout in webbot and command line tool is 20 secs. Can be
changed using the -timeout command line option. I have tested the patch on
linux, solaris, and digital unix but not yet on Windows NT. Help doing this
would be appreciated!

At the same time, these changes were committed as well:

a) Added support for etags in 201 responses. This will help avoiding the
lost update problem when multiple people are editing the same document.

b) Fixed a problem that prevented idle connections to be closed after 60
secs idle time. This functionality was there but because of a chance some
in a related place, it didn't execute as designed. Client side closes are a
lot easier to deal with as we don't get in to nasty recover resets of
pipelined requests.

c) Expanded progress flags in HTAlert to be 32 bit instead of 16 bit as I
was running out of flags. I don't think this affects anybody except from
people working on 16 bit machines. Btw, it would be nice to hear whether
anybody are working on 16 bit ports and what their status is.

Please try out these updates and see how they work.

Have fun!

Henrik
