Comments on: Hack for the encoding of a URL into another URL problem with Apache and mod_rewrite

I had similar issue with Apache 2 and Tomcat that sits behind.
First Apache didn’t allow / in URLs (give 404 error), after that I added AllowEncodedSlashes directive.
Then found problem with AllowEncodedSlashes because it doesn’t behave as described in Apache doc ( Apache does perform decoding automatically!), so my Tomcat receives ‘/’ instead of ‘/’ …. and after wasted day I did double encoding and that was the only solution.

I had almost the same problem.

My URL /myurl/searchText?accès

was transformed to

/myurl/searchText?acc�>Cs

The problem came from a rewrite rule. I added the NE flag on this rule and it fixed it !

I think the / “bug” you are referring to can be explained by the Apache AllowEncodedSlashes directive.

Thanks for your post. I used the “AllowEncodedSlashes On” described by FlorentG on my Apache 2.2/Win and it works!

Had the same issue, and double urlencoding worked great (everything is hidden behind mod_rewrite so they don’t see it anyway). Thanks.

The "/" issue is separate from the other generic mod_rewrite encoding issue - any URL with "/" in it before the query string in Apache 1.3 instantly returns a 404 before it gets to mod_rewrite, as an apparent security feature: Internal API documentation. This became a configuration option, AllowEncodedSlashes, in Apache 2.0.46, as FlorentG points out. Here's my own thoughts and solutions on the more generic issue.

RewriteRule flag [NE] can help to fix this.

If you have Apache >= 2.0.46, you can use the core directive “AllowEncodedSlashes On” to allow %2F in urls

Thanks for the bugfix, I had the same problem here.

Hi Mark,

Okay, and what is your version of Apache and what is the error?
