Just a suggestion : maybe one of the Tomcat/Java gurus here could first explain to what 
the maxPostSize attribute of the Connector really does relate ?
What /is/ being measured there ?
Is it, like, just the request's "Content-length" header, or is there a counter which 
really counts the bytes being read e.g.
(and yes, obviously, if this is limited to an "application/x-www-form-urlencoded" POST, 
then it wouldn't be just the Content-length header)
(and, if it covers a "multipart/form-data" POST, then is it the total body size, before of

after decoding the Base-64 encoded bits ?)
After all, this is a "Tomcat users" list, not a "Tomcat dev" list; so we can't really 
expect the public here to go delve into the Java code to find out.
