Some non-compatible changes were made to the Apache API in order to deal with HTTP/1.1 compatibility. It is possible that some modules will no longer work (specifically, those that process input using the POST or PUT methods). If you encounter a module that does not work, please contact the author. A programmer's note on the subject is available.
Additionally, some changes were made to the CGI environment that may cause some CGI scripts to work incorrectly. If you are experiencing trouble with a CGI that worked fine under Apache 1.1.1, please see our explanation of the changes.
New features with this release, as extensions of the Apache functionality. Because the core code has changed so significantly, there are certain liberties that earlier versions of Apache (and the NCSA daemon) took that recent Apache versions are pickier about - please check the compatibility notes if you have any problems.
In addition to a number of bug fixes and internal performance enhancements, *Apache 1.2 has the following specific new user features:
<Files>section allows directives to be enabled based on full filename, not just directory and URL. In addition,
<Files>sections can appear in
<Files>, along with
<Location>, can also now be based on regular expressions, not just simple prefix matching.
User-Agentstring of the browser. Combined with XSSI, this allows you to write browser-based conditional HTML documents.
mod_rewritemodule is now included. This module can provide powerful URL mapping, using regular expressions. There's nothing this module can't do!
mod_log_configincluded with earlier versions of Apache is now standard, and has been enhanced to allow logging of much more detail about the transaction, and can be used to open more than one log file at once (each of which can have a different log format). If you have Apache write any logs to a directory which is writable by anyone other than the user that starts the server, see the security tips document to be sure you aren't putting the security of your server at risk.
mod_cookiesincluded with previous versions of Apache has been renamed
ScriptLogallows you to now set up a log that records all input and output to failed CGI scripts. This includes environment variables, input headers, POST data, output, and more. This makes CGI scripts much easier to debug.
Optionsdirective can now add or remove options from those currently in force, rather than always replacing them.
-hcommand-line option now lists all the available directives.
mod_headersmodule can be used to set custom headers in the HTTP response. It can append to existing headers, replace them, or remove headers from the response.
<IfModule>section allows directives to be enabled only if a given module is loaded into the server.
Satisfyallows for more flexible access control configurations.
Satisfy, MaxKeepAliveRequests, RedirectPermanent and RedirectTemp, directives, and the following directives are now syntax-compatible with NCSA: AuthUserFile, AuthGroupFile, AuthDigestFile, KeepAlive and KeepAliveTimeout.
