Hi Daniel,

A while back I was testing mapscript with mod_perl and the biggest
problem I had was that the lexer was not thread-safe which caused the
script to die when quickly refreshing a page (see
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=339 for more
information). Has this issue been solved by the 4.0.2 release?


Many thanks,

Mark.
