* Revisions :
* $Log: cgi.c,v $
+ * Revision 1.75 2006/09/07 11:56:39 fabiankeil
+ * Mark cgi_send_user_manual as harmless,
+ * to fix the access denied problem Hal spotted.
+ * The manual has no secret content, therefore we
+ * don't have to care about "secure" referrers.
+ *
+ * Revision 1.74 2006/09/06 18:45:03 fabiankeil
+ * Incorporate modified version of Roland Rosenfeld's patch to
+ * optionally access the user-manual via Privoxy. Closes patch 679075.
+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.73 2006/08/03 02:46:41 david__schmidt
+ * Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
+ *
* Revision 1.72 2006/07/18 14:48:45 david__schmidt
* Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
* with what was really the latest development (the v_3_0_branch branch)

+ * If a temporary problem occurs and the user tries again after

* If-Modified-Since header with the content of the error page's

* 304 and the browser would display the outdated error message again and again.

- * As a last resort we set "Last-Modified" to Tim Berners-Lee's birthday,

* There is no need to let the useless If-Modified-Since header reach the
* server, it is therefore stripped by client_if_modified_since in parsers.c.
