Lighttpd

It seems that Google Adwords cookie (utmz) when containing polish characters like (?, ?, ?) crashes lighttpd with this error:

http_req.c.284: (trace) parsing failed at token ( [1]), header: GET /grupy/kategoria/9/ciaza/?utm_source=adwords&utm_medium=cpc&utm_campaign=ciaza_forum_twoja_pierwsza_ciaza&gclid=CJrZsY6SxJQCFQuGugodAUXTFA

This is why: utmctr=ci|a%20forum

This is google's fault because they should escape the string inside val utmcrt so it would look like this (ci%C4%85%C5%BCa+forum) - they do this everywhere exept adwords.

Also this cookie works in apache web server (doesn't crash it) :)

I will write to google about this matter.
