+ * - 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

+ * does not wish to use the "ACL" feature.
