server.go:2161: http: multiple response.WriteHeader calls #17

Closed ak2344 closed 8 years ago

Hi there,

Really appreciate your work. I'm getting weird errors like "server.go:2161: http: multiple response.WriteHeader calls" in my error log after normal looking GET requests to the index page. It's a been a bit hard to debug and replicate.

I know this may be outside the purview of the project, but if you have any pointers on where I can look to track this down, that would be really helpful.

Thanks!

Ah never mind, I figured it out. Thanks!

@ak2344 Would you mind sharing what was causing the issue? It may help someone else with the same problem. Also, if you have any more issues, I'd really appreciate you testing with the latest version: https://github.com/blue-jay/blueprint

No problem.

I had created my own middleware that checks the URL and forwards the user if it's invalid using http.Redirect(...). The problem was there wasn't a "return" after that so there was further writing to the headers later on.

Ah, I gotcha. Thanks!
