This is a library implemented in Go (Golang) that provides some functionality to deal with HTTP requests and headers.

Install in your ${GOPATH} using go get -u github.com/THREATINT/go-http.

Use ParseAcceptLanguage() to parse browser Accept-Language headers like

fr-CH, fr;q=0.9, en;q=0.8, de;q=0.7, *;q=0.5

Please see e.g. MDN (Mozilla Developer Network) for general information on Accept-Language.

ClientIP() returns the client ip address from HTTP headers. It works with X-Forwarded-For (used by most reverse proxies) and is aware of True-Client-IP and CF-Connecting-IP (both implemented by CloudFlare).

MimeTypeByExtension() provides a mapping for know file extension to mime type (e.g. .html -> text/html) based on the builtin mime.TypeByExtension and svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types.

Part of the source code for this functionality is generated by GenMimeType.py. (also provided in this repository)

We would love to hear from you! Please contact us at help@threatint.com for feedback and general requests. Kindly raise an issue in Github if you find a problem in the code.
