You say:=0ATomcat does not use any environment variables. The only settings=
 that=0Aaffect the interpretation of the URI are the "URIEncoding" and=0A"u=
seBody..." settings on the <Connector>. Are you using more than one=0Aconne=
ctor? Are you using Apache httpd out in front of Tomcat?=0A=0APerhaps the J=
VM does and so tomcat read them indirectly through it??=0A=0ACheers=0A=0A=
