=head1 DESCRIPTION |
52
|
|
|
|
|
|
|
|
53
|
|
|
|
|
|
|
In short: this removes all multiple slashes from your B. Read on, |
54
|
|
|
|
|
|
|
if you care why. |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
Multiple slashes in requests are a common problem, which many share. |
57
|
|
|
|
|
|
|
Apparently, the RFC states that you should be able to expect different results |
58
|
|
|
|
|
|
|
from I and I (notice the second slash), so |
59
|
|
|
|
|
|
|
if the frameworks wish to maintain RFC compatibility, they cannot remove those |
60
|
|
|
|
|
|
|
extra slashes for you. |
61
|
|
|
|
|
|
|
|
62
|
|
|
|
|
|
|
While you can handle this issue in a reverse proxy, in a rewrite module or |
63
|
|
|
|
|
|
|
in your code, I find it more comfortable to have Plack take care of it in the |
64
|
|
|
|
|
|
|
thin layer called Middlewares. |
65
|
|
|
|
|
|
|
|
66
|
|
|
|
|
|
|
By enabling this middleware, all multiple slashes in your requests will |
67
|
|
|
|
|
|
|
automatically be cut. I/hello///world> becomes I. Simple as |
68
|
|
|
|
|
|
|
that. |

=head1 ORIGIN |
71
|
|
|
|
|
|
|
|
72
|
|
|
|
|
|
|
This Plack middleware was written originally after the issue was raised in |
73
|
|
|
|
|
|
|
the L (L) community. |
74
|
|
|
|
|
|
|
|
75
|
|
|
|
|
|
|
If you're using Dancer, this is the prefered way to handle this issue. |
