When user calls res.writeHead(200, undefined, {'foo': 'bar'}),
compression middleware was overwriting those headers by calling
writeHead again without the headers. Check res._header to detect
if writeHead was already called.

Bug (compression#254)
When user calls
res.writeHead(200, undefined, {'foo': 'bar'})with custom headers, the compression middleware overwrites those headers when it callsthis.writeHead(this.statusCode)without passing the headers.Fix
Check
res._headerto detect if writeHead was already called with headers, and skip calling writeHead again if headers exist.Verification
res.writeHead(200, undefined, {'foo': 'bar'})
