Three more questions:
* Which is preferrable -- Url_ReadPost or Httpd_ReadPostData?
* Where (ha! :) is all of this stuff documented? The book chapter is kind of
skimpy..
* The last version of the web server on dev.scriptics.com is 3.1. Can you give
an idea
how the 3.2 "cleaner way" works?
Thanks for all of this good stuff! I understand better now about httpd.tcl
being a "main program" and not reloadable.
One more Q: do you have performance data to compare TclHttpd with AOLserver? I
know this is not a list to discuss AOLserver, but just a small issue -- is the
Tcl event loop active in AOLserver?
