12 Revision 212.10 2000/09/14 11:43:37 error
13 Replace occurrences of % throughout the HTML with %% so as to be friendly
14 to HP/UX printf() and possibly others.
16 Revision 212.9 2000/09/13 04:13:59 ajc
17 * Completed the initial hack of the variable substitution template thingy.

49 Revision 211.19 2000/05/18 02:33:39 ajc
50 * Don't call whobbs() directly after changing masq room/host, it screws up the
51 refresh. It now calls an HTTP redirect page instead.
52 * added http_redirect(char *url) function to accomplish the above
54 Revision 211.18 2000/05/08 17:24:32 ajc
55 * Removed HTTP date fields because it was confusing browser caches (weird)

68 * End the session after displaying robots.txt or nocookies.html, to prevent
69 big session logjams when either of these conditions are met
71 Revision 211.14 2000/04/15 15:43:46 nbryant
72 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

162 Revision 1.111 1999/12/03 17:59:53 ajc
163 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
164 pseudocode so the build is currently broken.
166 Revision 1.110 1999/12/03 16:37:46 ajc

169 Revision 1.109 1999/12/03 05:09:54 ajc
170 * Rewrote the HTTP engine and application coupling to run in a worker thread
171 model and to run as a single multithreaded program (eliminated helper

196 Revision 1.101 1999/10/06 02:44:02 ajc
197 * Per Nick's request, removed the key bindings stuff. He knows how to fit
198 it back in when it's fixed. Also added more attempts at cache disabling,
199 but it still doesn't work in the StarOffice browser. I don't know why.
201 Revision 1.100 1999/10/02 03:26:14 ajc
202 * Merged in Nick's bit of JavaScript to handle key commands.
203 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

262 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
263 * Fixed the behavior of the "forget room" routine, to properly handle
264 the transition back to the Lobby after it's all done.
265 * Added ExpressMessageCat() to allow code to send the user messages
266 along with incoming express messages
267 * WebCit now sends the name of the end user's browser as the client
268 name in a Citadel IDEN command rather than its own name.
270 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

282 * Replaced _most_ gotoroom() calls with smart_goto(), a version

300 Changed who.c to use urlescputs() rather than escputs()
301 in urls so GOTOs and User Profiles work when the string has a
304 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
305 http://www.webreference.com/dhtml/column18/menuFrLoad.html
306 How to cause "onLoad=" to cause a sibling frame to refresh without
307 having to use the nonportable HTTP "Window-Target:" directive. Began
308 implementation of this; it should allow portable NS/IE compatibility.

314 * webcit.c: modified getz() to *exit* the program when fgets()
315 returns an error. This is actually the desired behavior; it would
316 otherwise busy-loop forever on a broken pipe.
318 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
319 * webcit.c: added to getz() the ability to return an error code;

328 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
329 * context_loop.c: warning fix
330 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
332 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
333 * Resolve the name of the connecting host and pass it on to Citadel
335 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
336 * wDumpContent() is now responsible for </BODY></HTML> most of the
337 time (parameter settable) so that the main menu can easily be
338 embedded in every page when running in noframes mode
339 * noframes mode selection is now carried in the cookie
341 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

348 from the main Citadel tree, to pay attention to floor/room ordering
350 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
351 * Modified the back end of mime_parser to use callbacks instead of
352 doing something specific. Now we can use it elsewhere.
354 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
355 * Fixed the bugs in "Site-wide configuration"

362 * Removed wc_host and wc_port cookies.
363 * Added an "edit your session" screen to change your wholisting.

366 * Added "enter registration"
367 * Set up automatic trigger of Enter Registration when the server
369 * Established that a one-to-one WebCit/Citadel correspondence will
370 be required. No big deal due to shared code segments.
371 * Added "change password"
372 * Added networking configuration screens. These still need testing.
373 * Added a "kill session" link to each line of the wholist when
374 logged in as an aide, and the screens to perform this operation.
376 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

385 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
386 * Wrote mime_parser.c for handling of image uploads. This will also
387 be used in future Citadel MIME projects.
389 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
390 * Fixed a bug in the room banner display code

419 * automatically regenerate Makefile when Makefile.in changes
421 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
422 * context_loop.c: Moved "remove session" into its own function.
423 Check for dead webcit child process before each transaction.

443 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
444 * context_loop.c: After fork(), child process closes the HTTP socket
445 so when the parent process closes it, it actually _does_ close.
446 Otherwise, aIEeeee and possibly other browsers will hang.
447 * Added support for graphics images retrieved from the Citadel server.
448 * Set up login banner graphic and background image graphic

458 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
459 * Discovered that the HTTP socket problem is related to a socket that
460 isn't properly lingering on close. Temporarily hacked a sleep(10)
461 into context_loop.c until it is figured out.

464 * Did a little debugging, still trying to figure out why logging in
