[Erlyaws-list] yaws_api:request_url() fails to parse a query with '?' in it

[Vlad S. <vs...@73...>]

Hi,

per RFC3986 (section 3.4), the query section of the URL starts with the 
first '?' after the path and ends with the first '#' character. However, 
yaws_api:request_url() fails to handle a case when there are multiple 
'?' characters in the URL. For example, the following request will cause 
a trap:

http://www.example.com/api/XXX?a=b?a=d

Here is a trivial patch to fix it:
