*
* Revisions :
* $Log: jcc.c,v $
+ * Revision 1.26 2001/07/18 12:31:36 oes
+ * cosmetics
+ *
+ * Revision 1.25 2001/07/15 19:43:49 jongfoster
+ * Supports POSIX threads.
+ * Also removed some unused #includes.
+ *
+ * Revision 1.24 2001/07/13 14:00:40 oes
+ * - Generic content modification scheme:
+ * Each feature has its own applicability flag that is set
+ * from csp->action->flags.
+ * Replaced the "filtering" int flag , by a function pointer
+ * "content_filter" to the function that will do the content
+ * modification. If it is != NULL, the document will be buffered
+ * and processed through *content_filter, which must set
+ * csp->content_length and return a modified copy of the body
+ * or return NULL (on failiure).
+ * - Changed csp->is_text to the more generic bitmap csp->content_type
+ * which can currently take the valued CT_TEXT or CT_GIF
+ * - Reformatting etc
+ * - Removed all #ifdef PCRS
+ *
+ * Revision 1.23 2001/07/02 02:28:25 iwanttokeepanon
+ * Added "#ifdef ACL_FILES" conditional compilation to line 1291 to exclude
+ * the `block_acl' call. This prevents a compilation error when the user
+ * does not wish to use the "ACL" feature.
+ *
+ * Revision 1.22 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.21 2001/06/29 13:29:36 oes
+ * - Cleaned up, improved comments
+ * - Unified all possible interceptors (CGI,
+ * block, trust, fast_redirect) in one
+ * place, with one (CGI) answer generation
+ * mechansim. Much clearer now.
+ * - Removed the GIF image generation, which
+ * is now done in filters.c:block_url()
+ * - Made error conditions like domain lookup
+ * failiure or (various) problems while talking
+ * to the server use cgi.c:error_response()
+ * instead of generating HTML/HTTP in chat() (yuck!)
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.20 2001/06/09 10:55:28 jongfoster
+ * Changing BUFSIZ ==> BUFFER_SIZE
+ *
+ * Revision 1.19 2001/06/07 23:12:52 jongfoster
+ * Replacing function pointer in struct gateway with a directly
+ * called function forwarded_connect().
+ * Replacing struct gateway with struct forward_spec
+ *
+ * Revision 1.18 2001/06/03 19:12:16 oes
+ * introduced new cgi handling
+ *
+ * Revision 1.17 2001/06/01 20:07:23 jongfoster
+ * Now uses action +image-blocker{} rather than config->tinygif
+ *
+ * Revision 1.16 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.15 2001/05/31 21:24:47 jongfoster
+ * Changed "permission" to "action" throughout.
+ * Removed DEFAULT_USER_AGENT - it must now be specified manually.
+ * Moved vanilla wafer check into chat(), since we must now
+ * decide whether or not to add it based on the URL.
+ *
+ * Revision 1.14 2001/05/29 20:14:01 joergs
+ * AmigaOS bugfix: PCRS needs a lot of stack, stacksize for child threads
+ * increased.
+ *
* Revision 1.13 2001/05/29 09:50:24 jongfoster
* Unified blocklist/imagelist/permissionslist.
* File format is still under discussion, but the internal changes
