Description

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.

It's Google Adwords cookie, not Adsense

%C4%85%C5%BC are all characters that are allowed, so they shouldn't be a problem. we had other reports of them being control chars (like %05), which we will never allow.

What's the purpose to make such strict checks against de-facto obsolete RFC? In real world google determines what is standard, not RFC. This is really huge issue as lost adword clicks due to 400 = lost real money. This issue prevents using unpatched lighttpd on production.

No, i do NOT change code just to workaround google bugs. Oh, and while we are at it: I don't like adwords.

if you think google practice sets the standards, then go use their software, but don't complain here.

No, he stated that he got "utmctr=ci|a%20forum". I think it's the same problem as:

I was under impression that lighttpd is targeted to e-commerce sites too where Adwords are de-facto way of doing business. Sorry, I was wrong.

Sergey, usego: have you tried contacting Google so they fix the cookies in Adwords? Because this is where the bug really is.

And regarding the last snarky remark: yes you were indeed wrong. Lighty is not targeted to E-Commerce sites. Lighty is not targeted to any specific kind of site in any way. Lighty is targeted for users who need a lightweight and fast webserver. Google does not determine what the standard is. The HTTP RFC is not de-facto obsolete.

FYI: in lighttpd 1.4.40, you can now set server.http-parseopt-header-strict = "disable"

With the default (strict header parsing enabled), lighttpd 1.4.x will return 400 Bad Request for such a request.
