Functions

func GZip

func GZip(h http.Handler) http.Handler

GZip returns a handler which gzip's the response for all requests which accept that encoding.

func Inject

func Inject(script string, handler http.Handler) http.Handler

Inject appends JavaScript to the body of all HTML responses. It buffers all responses in memory (so use it selectively). It prints all parsing errors using the log package's Print function rather than returning 500s.

func Log

func Log(log io.Writer, h http.Handler) http.Handler

func NoCaching

func NoCaching(handler http.Handler) http.Handler

func ProxyRedirect

func ProxyRedirect(scheme, basePath string, handler http.Handler) http.Handler

ProxyRedirect joins basePath to the location header of all redirects generated the by handler. It also changes the scheme as provided.

p := httputil.NewSingleHostReverseProxy(u)
// force redirects to use https and prepend "/foo/bar" to all paths
h := middleware.ProxyRedirect("https", "/foo/bar", p)
