* $Log: config.c,v $
* Revision 2.0 2006/02/01 11:45:28 roseg
* Enhancements:
* - new configuration file syntax, offering significant improvements.
* - the ability to define listener-specific back-ends. In most cases this
* should eliminate the need for multiple Pound instances.
* - a new type of back-end: the redirector allows you to respond with a
* redirect without involving any back-end server.
* - most "secondary" properties (such as error messages, client time-out,
* etc.) are now private to listeners.
* - HAport has an optional address, different from the main back-end
* - added a -V flag for version
* - session keeping on a specific Header
*
* Revision 1.10 2006/02/01 11:19:51 roseg
* Enhancements:

* - added support for HTTPSHeaders 3 (no verify)
*
* Problems fixed:
* - fixed bug if multiple listening ports/addresses
* - fixed memory leak in SSL
* - flush stdout (if used) after each log message
* - assumes only 304, 305 and 306 codes to have no content
* - fixed problem with delays in 302 without content

*
* Enhancements:

* - added supervisor process disable configuration flag
* - tweak for the Location rewriting code (only look at current GROUP)
* - improved print-out for client certificate information
*
* Revision 1.7 2004/03/24 06:59:59 roseg
* Fixed bug in X-SSL-CIPHER description
* Changed README to stx format for consistency
* Addedd X-SSL-certificate with full client certificate
* Improved the response times on HTTP/0.9 (content without Content-length)
* Improved response granularity on above - using unbuffered BIO now
* Fixed problem with IE/SSL (SSL_set_shutdown)
* Avoid error messages on premature EOF from client
* Fixed HeadRemove code so all headers are checked without exception
* Improved autoconf detection
*
* Revision 1.6 2003/11/30 22:56:26 roseg
* Callback for RSA ephemeral keys:
* - generated in a separate thread
* - used if required (IE 5.0?)
* New X-SSL-cipher header encryption level/method
* Added CheckURL parameter in config file
* - perform syntax check only if value 1 (default 0)
* Allow for empty query/param strings in URL syntax
* Additional SSL engine loading code
* Added parameter for CA certificates
* - CA list is sent to client
* Verify client certificates up to given depth
* Fixed vulnerability in syslog handling
*
* Revision 1.5 2003/10/14 08:32:03 roseg
* Session by Basic Authentication:
* Session BASIC parameter added
* Syntax checking of request.
* User-defined request character set(s):
* Parameters CSsegment, CSparameter, CSqid, CSqval
* Request size limit:
* Parameter MaxRequest
* Single log function rather than #ifdefs.
* Added LogLevel 4 (same as 3 but without the virtual host info).
* Added HeadRemove directive (allows to delete a header from requests).
* Location rewriting on redirect:
* if the request contains a Header directive
* and the response is codes 301, 302, 303, 307
* and the Location in the response is to a known host
* then the Location header in the response will be rewritten to point
* to the Pound protocol/port itself
*
* Revision 1.4 2003/04/24 13:40:11 roseg
