 * Revisions   :
 *    $Log: parsers.h,v $
 *    Revision 1.3  2001/05/26 13:39:32  jongfoster
 *    Only crunches Content-Length header if applying RE filtering.
 *    Without this fix, Microsoft Windows Update wouldn't work.
 *
 *    Revision 1.2  2001/05/20 01:21:20  jongfoster
 *    Version 2.9.4 checkin.
 *    - Merged popupfile and cookiefile, and added control over PCRS
 *      filtering, in new "permissionsfile".
 *    - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
 *      file error you now get a message box (in the Win32 GUI) rather
 *      than the program exiting with no explanation.
 *    - Made killpopup use the PCRS MIME-type checking and HTTP-header
 *      skipping.
 *    - Removed tabs from "config"
 *    - Moved duplicated url parsing code in "loaders.c" to a new funcition.
 *    - Bumped up version number.
 *
 *    Revision 1.1.1.1  2001/05/15 13:59:01  oes
 *    Initial import of version 2.9.3 source tree
