Description

We are running http://m.nokaut.pl/ mobile price comparison website on lighttpd 1.5-svn.

Everything works OK with popular browsers, Opera Mobile and some built-in mobile browsers (eg. Motorola, Samsung), but there is a MAJOR problem with all the requests from Nokia built-in web browser. All such requests receive "HTTP/1.1 400 Bad Request" error. I guess that it is caused by some not-standard HTTP headers.

Here is the full connection log (sniffed by ettercap):

From what I can see, the problem is that your browser sends a Content-Length header during a GET request. (GET requests cannot contain a message-body; according to RFC2068 the Content-Length header signals that a message-body follows)

Lines 542-545 of request.c: 

	case HTTP_METHOD_GET:
	case HTTP_METHOD_HEAD:
		/* content-length is forbidden for those */
		if (con->request.content_length != -1) {

I guess you could change it to something like this, to be more lenient. 

		if (con->request.content_length <= 0) {

(That should be a > instead of a <=, sorry)

After changing that line, everything works well. We will contact Nokia and ask them to change their software to be RFC-compatible, but I think that the patch above should be included in main lighttpd source.

The same RFC incompatibility exists with the popular PHP SOAP library, nuSOAP. Here is a fix if anyone finds this page while trying to figure out the 400 errors with nuSOAP, like me :)

Also occurs on some Motorola phones

Add/Change #1351 (lighttpd returns "400 Bad Request" for Nokia web browser request)
