Remove multiple slashes in your paths automatically
PlackMiddlewareNoMultipleSlashes removes all multiple slashes from your PATH_INFO.
Multiple slashes in requests are a common problem, which many share. Apparently, the RFC states that you should be able to expect different results from http//server/ and http//server// notice the second slash, so if the frameworks wish to maintain RFC compatibility, they cannot remove those extra slashes for you.
While you can handle this issue in a reverse proxy, in a rewrite module or in your code, I find it more comfortable to have Plack take care of it in the thin layer called Middlewares.
By enabling this middleware, all multiple slashes in your requests will automatically be cut. //hello///world becomes /hello/world. Simple as that.
