Plack::Middleware::NoMultipleSlashes - Remove multiple slashes in your paths automatically


version 0.001


Pure Plack:

    # in your app.psgi
    use Plack::Builder;

    my $app = sub { ... };

    builder {
        enable 'NoMultipleSlashes';

Or in your Dancer app:

    # in config.yml
        - [ NoMultipleSlashes ]


In short: this removes all multiple slashes from your PATH_INFO. Read on, if you care why.

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.


This Plack middleware was written originally after the issue was raised in the Dancer ( community.

If you're using Dancer, this is the prefered way to handle this issue.
