Don't call WriteHeader more than once

[jvshahid]

This message is all over the logs:

http: multiple response.WriteHeader calls

We shouldn't be calling WriteHeader more than once.

I don't think this is happening anymore. Closing for now.

this bug still exists (or came back), I am not sure how I triggered it but each time I do a get request my console is flooded by this warning (I am running on master).

Edit: I don't have it with 0.4.0 though

[schmurfy]

I spoke too quickly now I have it on 0.4.0 too, I am not sure but it seems linked to parallel requests.
As long as I was only making one request at a time no warning were shown but as soon as I started to play with parallel requests (without reusing the connection) the warning started to show and it seems that when it shows the requests fails from the client point of view.

@schmurfy Thanks for the update. Reopening this and we'll take a look!

I get back the no response part, otherwise I tried to narrow down when exactly I get the warning but the end result is.. I have no idea xD

I get this often when I send an invalid time format.

[jvshahid]

Do you still get it with the fix that i just pushed ?
