Because the core code has + changed so significantly, there are certain liberties that + earlier versions of Apache (and the NCSA daemon) took that + Apache 1.0 is pickier about - please check the <a + href="misc/compat_notes.html">compatibility notes</a> if you + have any problems.</p> + + <ul> + <li> + API for server extensions --- see below for a brief sermon + on philosophy, or see <a + href="misc/API.html">src/API.html</a> for an actual + overview. Most server functionality (including includes, + CGI, and most forms of access control) are actually + implemented as API-conformant modules; you can also do + other neat stuff (we've included a sample module, for + instance, which one of us is using to track click-trails + using the <a + href="http://home.netscape.com/newsref/std/cookie_spec.html"> + Netscape cookie mechanism</a>, for visitors who come in + through Netscape clients). <a + href="mod/mod_dld.html">Modules</a> can also be loaded + dynamically using GNU DLD. + + <p>The API is not yet quite stable (see src/TODO for some + possible changes), but anything done now will be easily + adapted for future versions --- after all, we have more + modules to adapt than you do.</p> + </li> + + <li><a href="process-model.html">New Process Model - much + less forking, no fixed number of children.</a> We found that + many people were using values for "MaxServers" either too + high or too low, and were hanging themselves on it. The model + we adopted is still based on long-lived minimal-forking + processes, but instead of specifying one number of persistent + processes, the web-master specifies a maximum and minimum + number of processes to be "spare" - every couple of seconds + the parent checks the actual number of spare servers and + adjusts accordingly. This should keep the number of servers + concurrently running relatively low while still ensuring + minimal forking.</li> + + <li><a href="vhosts/"><VirtualHost> (the configuration + directive for multiple-homed servers)</a> is more general + now. Just about any srm.conf or httpd.conf command can go in + a <Virtualhost> section, with the following specific + exceptions: ServerType, UserId, GroupId, StartServers, + MaxRequestsPerChild, BindAddress, PidFile, TypesConfig, + ServerRoot.</li> + + <li><a href="content-negotiation.html">Support for content + negotiation of languages through MultiViews</a> (*.fr, *.de, + *.en suffixes), via the new AddLanguage and LanguagePriority + commands (code written by Florent Guillaume, + guillaum@clipper.ens.fr).</li> + + <li>Significant internal cleanups and rearrangements. The two + externally visible consequences of this are that just about + all of the unchecked fixed limits are gone, and that the + server is somewhat pickier about config file syntax (noting + and complaining about extraneous command arguments or other + stuff at the end of command lines).</li> + + <li>XBITHACK is a run-time option, and can be selectively + enabled per directory --- the -DXBITHACK compile-time option + just changes the default. The command which configures it is + "XBitHack", which is allowed everywhere "Options" is; this + takes an argument --- "XBitHack Off" turns it off; "XBitHack + On" gets you the NCSA -DXBITHACK behavior; and "XBitHack + Full" gets you the Apache GXBIT stuff on top of that. + (-DXBITHACK makes "Full" the default; otherwise, it defaults + "Off").</li> + + <li>TransferLog can specify a program which gets the log + entries piped to it, a la 'TransferLog "| + /var/www/my-perl-script -arg valu"' --- this should give the + same SIGTERM/pause/SIGKILL treatment to the logging process + on server restarts that a CGI script gets on an aborted + request. NB the server is counting on the logging process to + work, and will probably hang or worse if it dies.</li> + + <li><a href="mod/mod_log_config.html">Configurable logging + module</a> --- this is a replacement for the standard + plane-jane Common Log Format code, which supports a LogFormat + directive which allows you to control the formatting of + entries in the TransferLog, and add some new items if you + like (in particular, Referer and User-Agent). + EXPERIMENTAL.</li> + </ul> + <hr /> + + <h2>Other features of Apache</h2> + + <ul> + <li><a href="mod/mod_dld.html">Dynamically loading modules + using GNU DLD</a></li> + + <li><a href="mod/mod_imap.html">Imagemap Module</a></li> + + <li><a href="mod/mod_dir.html#directoryindex">Multiple + DirectoryIndex filenames</a></li> + + <li><a href="mod/mod_asis.html">"Send as is" file + types</a></li> + + <li><a href="mod/mod_include.html#xbithack">XBITHACK last + modified</a></li> + </ul> + <!--#include virtual="footer.html" --> + </body> +</html> + |
