Hello everyone: I'm using golang with Win10. Now I'm trying to write a web browser. The version of the golang which I am using is 1.12.9. Here is the problem that I'm encountering: Here <https://play.golang.org/p/rE-4CQnigEA> is the code. The code couldn't run with "The Go Playground", while it works with the "Visual Studio Code". The results are what I want. However, there appears the message "http: superfluous response.WriteHeader call from main.login" with line 34 and line 37. If I remove these two lines, the results won't serve the file. I have no idea how to avoid the warning. Here <https://play.golang.org/p/DLwoNcPLE_r> are the HTML files.
Any help is appreciated. Thank you very much! Max -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
