[webkit-dev] How to set a cookie for a url ?

[Mark Pauley]

I think the problem here is with your expires= value.  The output  
format of 'date' is also a good reference.

We currently support the following formats for date strings: ascii  
time, RFC1123 and RFC2616.

Please feel free to file a bug if there is another widely supported  
date format that we don't support.
