+
+<para>
+ To match requests that do not have a certain tag, specify a negative tag pattern
+ by prefixing the tag pattern line with either <quote>NO-REQUEST-TAG:</quote>
+ or <quote>NO-RESPONSE-TAG:</quote> instead of <quote>TAG:</quote>.
+</para>
+
+<para>
+ Negative tag patterns created with <quote>NO-REQUEST-TAG:</quote> are checked
+ after all client headers are scanned, the ones created with <quote>NO-RESPONSE-TAG:</quote>
+ are checked after all server headers are scanned. In both cases all the created
+ tags are considered.
