  * Revisions   :
  *    $Log: jcc.c,v $
+ *    Revision 1.180  2008/05/21 15:26:32  fabiankeil
+ *    - Mark csp as immutable for send_crunch_response().
+ *    - Fix comment spelling.
+ *
+ *    Revision 1.179  2008/05/20 20:13:32  fabiankeil
+ *    Factor update_server_headers() out of sed(), ditch the
+ *    first_run hack and make server_patterns_light static.
+ *
+ *    Revision 1.178  2008/05/10 13:23:38  fabiankeil
+ *    Don't provide get_header() with the whole client state
+ *    structure when it only needs access to csp->iob.
+ *
+ *    Revision 1.177  2008/05/10 11:51:12  fabiankeil
+ *    Make the "read the rest of the headers" loop a bit more readable.
+ *
  *    Revision 1.176  2008/05/10 11:37:57  fabiankeil
  *    - Instead of logging when the IIS5 hack is enabled, log when it fails.
  *    - Remove useless comment.
