* Revisions :
* $Log: parsers.c,v $
+ * Revision 1.123 2008/03/29 12:13:46 fabiankeil
+ * Remove send-wafer and send-vanilla-wafer actions.
+ *
+ * Revision 1.122 2008/03/28 15:13:39 fabiankeil
+ * Remove inspect-jpegs action.
+ *
+ * Revision 1.121 2008/01/05 21:37:03 fabiankeil
+ * Let client_range() also handle Request-Range headers
+ * which apparently are still supported by many servers.
+ *
+ * Revision 1.120 2008/01/04 17:43:45 fabiankeil
+ * Improve the warning messages that get logged if the action files
+ * "enable" filters but no filters of that type have been loaded.
+ *
+ * Revision 1.119 2007/12/28 18:32:51 fabiankeil
+ * In server_content_type():
+ * - Don't require leading white space when detecting image content types.
+ * - Change '... not replaced ...' message to sound less crazy if the text
+ * type actually is 'text/plain'.
+ * - Mark the 'text/plain == binary data' assumption for removal.
+ * - Remove a bunch of trailing white space.
+ *
* Revision 1.118 2007/12/28 16:56:35 fabiankeil
* Minor server_content_disposition() changes:
* - Don't regenerate the header name all lower-case.
