"allSPDYHeaderFields" get path error

[szrexzhu]

I try to use CocoaSPDY visit our SPDY Proxy Server in my QQ Browser，meet a bug:

Visit http://m.sohu.com/n/452167131/?wscrid=15084_2，get a 301 redirect，the reason is that we have a error path:'/n/452167131?wscrid=15084_2',lost '/' when we use 'url.path'.

- (NSDictionary *)allSPDYHeaderFields
{
    NSDictionary *httpHeaders = self.allHTTPHeaderFields;
    NSURL *url = self.URL;

    static NSSet *invalidKeys;
    static NSSet *reservedKeys;
    static dispatch_once_t initialized;
    dispatch_once(&initialized, ^{
        invalidKeys = [[NSSet alloc] initWithObjects:
            @"connection", @"keep-alive", @"proxy-connection", @"transfer-encoding", nil
        ];

        reservedKeys = [[NSSet alloc] initWithObjects:
            @"method", @"path", @"version", @"host", @"scheme", nil
        ];
    });

This looks like the code out of the 'master' branch. The 'develop' branch has changed this a bit, to use NSURLComponents for the url pieces. It seems to behave correctly for the path segment of your url. You may want to try running the 'develop' branch code for this issue, and possibly your others. In the meantime, I'll merge 'develop' into 'master' and create a new release but it may take a few weeks.
