+ * 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.
* the current time doesn't exactly forbid caching, it just
* requires the client to revalidate the cached copy.

+ * If a temporary problem occurs and the user tries again after
* getting Privoxy's error message, a compliant browser may set the
* If-Modified-Since header with the content of the error page's
* Last-Modified header. More often than not, the document on the server
* is older than Privoxy's error message, the server would send status code
* 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,
- * which predates the age of any page on the web and can be safely used to
- * "revalidate" without getting a status code 304.
+ * For documents delivered with status code 404 or 503 we set "Last-Modified"
+ * to Tim Berners-Lee's birthday, which predates the age of any page on the web
+ * and can be safely used to "revalidate" without getting a status code 304.
*
* 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.
