Basic url rewrite withRewrite Rules Module

I'm trying to redirect the url "" to "".

I have successfully gotten "foo" to redirect to "bar" (as a test) as follows:

RewriteRule foo bar

So the module seems to be working. I think it's my rewrite syntax that is incorrect. When I write: 

RewriteRule foo foo/sub

...I get the following error:

HttpException (0x80004005): The length of the URL for this request exceeds the configured maxUrlLength value


Without the rewrite rules enabled, directly accessing works properly. So I'm not sure what's wrong with my second example, but it's not working

Thanks for any help.

The problem is the rewrite engine will keep running the rewrites over and over until it's told to stop. You're creating a recursive rewrite like this:






So eventually it's hitting the length limit.

Change your rule to:

RewriteRule foo foo/sub [L]

The [L] means "last", telling the engine to stop processing.

Guess I need to brush up on my mod_rewrite :-)

Needed to add one addition (the trailing $) to what you suggested:

RewriteRule foo$ foo/sub [L]


So [L] tells engine to stop processing, and I'm guessing $ (regex "end") does something similar for the pattern. Once again, randompete to the rescue. Thanks!

A quick follow up:

I can't get the second url to work.

Urls to test (Simulations tab):


RewriteRule ^foo$ foo/bar/zap [L]
RewriteRule ^foo/bar$ foo/bar/zap [L]

The idea is that I need both urls to resolve to foo/bar/zap. Each rewrite rule works INDIVIDUALLY, but with both of them in there, only the first one works (foo resolves to foo/bar/zap, but foo/bar does not). 

Thanks, again.

It seems the version on the gallery is not the latest one, fixing this issue and a bunch of others. Let me update it.

The new version is online, you rule seems good and should work with the update.

Thanks so much for the update, sebastien. Is there something I need to do to ensure that I have the latest? I just tried: 1) installing from Gallery via Admin, and 2) downloading and then "Install module from computer" option (Nuget package). (also did Clean and Rebuild of Solution)

The "Simulate" tab indicates that these rules will resolve to the foo/bar/zap url correctly. Both indicate "Transfer to foo/bar/zap".

However, actually navigating to foo/bar takes me to foo/foo/bar/zap

In other words, it's still not working for me.

Check the Module.txt file, it should be 1.2.4

I verified that I have the latest code (version of the Module.txt is 1.2.4). 

Here's what I'm noticing: 

http://orchard-dev/headquarters takes me to 
(which is correct)

http://orchard-dev/headquarters/green-components tries to take me to 
(notice the repeated "headquarters" in last url)

Here are my rules:

RewriteRule /headquarters$ headquarters/green-components/geothermal-hvac-system [L]
RewriteRule /headquarters/green-components$ headquarters/green-components/geothermal-hvac-system [L]

I honestly don't know whether this is the Module code or just something wrong w/ my rules.
