Double escaping along with URL rewrite in IIS - iis

Question

I have a URL(auto-generated) which is having plus( + ) in the path and I was getting 404 for that.
I searched for a while a found that we can enable double encoding using the following:
<security>
<requestFiltering allowDoubleEscaping="true" />
</security>
The problem I am facing is with the rewrite rule for that URL, the plus is being replaced with whitespace in the captured groups:
<rule name="Test Page Rewrite" stopProcessing="true">
<match url="^test/([\-a-z0-9_.+]+)$" ignoreCase="true" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="test/index.cfm?p1={R:1}" />
</rule>
e.g.,
For URL: /test/test+page
The URL parameter available on the page is p1: test page
Is there any workaround for this to capture from the requested URL so that the URL parameter p1 will have a value of test+page(original)?

Answer 1

You can use UrlEncode function. This rule should work for you:
<rule name="Test Page Rewrite" stopProcessing="true">
<match url="^test/([\-a-z0-9_.+]+)$" ignoreCase="true" />
<conditions>
<add input="{REQUEST_URI}" pattern="^/test/index.cfm" negate="true" />
</conditions>
<action type="Rewrite" url="test/index.cfm?p1={UrlEncode:{R:1}}" />
</rule>
