Hi, It seems like some part of the HTTP protocol cannot be understand by the webserver. What you can do is the following : before "Lexer.input" in parse_http_request, add the following lines : var str = IO.read_all in; printf "=====%s=====" str; var in = IO.read_string str; This will should all HTTP requests before parsing them. Please send me the output of the HTTP requests that fails, or try to understand why it fails by checking the grammar rules (see Lexer.build calls in Webserver.nml) Best, Nicolas Best, Nicolas -- Neko : One VM to run them all (http://nekovm.org)
