-# Wait max 10 seconds for the first byte of the request line+headers
+# mod_reqtimeout limits the time waiting on the client to prevent an
+# attacker from causing a denial of service by opening many connections
+# but not sending requests. This file tries to give a sensible default
+# configuration, but it may be necessary to tune the timeout values to
+# the actual situation. Note that it is also possible to configure
+# mod_reqtimeout per virtual host.

+# Wait max 20 seconds for the first byte of the request line+headers
 # From then, require a minimum data rate of 500 bytes/s, but don't
-# wait longer than 20 seconds in total.

+# wait longer than 40 seconds in total.
+# Note: Lower timeouts may make sense on non-ssl virtual hosts but can
+# cause problem with ssl enabled virtual hosts: This timeout includes
+# the time a browser may need to fetch the CRL for the certificate. If
+# the CRL server is not reachable, it may take more than 10 seconds
+# until the browser gives up.
