I have not explored this, so these comments are based on the
documentation.
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access_Log_Valve
Turns on conditional logging. If set, requests will be logged only
if ServletRequest.getAttribute() is null. For example, if this
value is set to junk, then a particular request will only be
logged if ServletRequest.getAttribute("junk") == null. The use of
Filters is an easy way to set/unset the attribute in the
ServletRequest on many different requests.
So . . .
1. multiple URL patterns to add an attribute - exclude /*/iaahb
2. rewrite the filter to:
a. examine the URI
b. add the attribute if it does not include /*/iaahb
c. set the URL pattern to /*
3. Use tuckey.org's URL rewrite filter (http://tuckey.org/urlrewrite/)
a. use a negative regular expression match
b. set the attribute value for all URI patterns except /*/iaahb
