Replace %5E in URL using IIS Rewrite - ios

Question

I have the following problem:
I send a request via HttpResponse.Redirect method to a web application:
http(s)://localhost/application?arg1=abc^def
This works pretty fine on IE/Edge/Chrome/Firefox. But on Safari I get the problem that the request is sent as following encoded string:
http(s)://localhost/application.aspx?arg1=abc%5Edef
The application does not like/accept that and I am not able to perform changes on the application.
Is it possible to rewrite the URL on the webserver where the application is hosted by IIS Rewrite module somehow?
I tried already to create a rule with following regex pattern:
^application?(.\*)%5E(.\*)
and the following action:
Rewrite URL:
application.aspx?{R:1}%5E{R:2}
...but this does not seem to work (although the regex pattern has passed the "Test Pattern" test)
Many thanks in advance!

This is because there is a problem with your rewrite rules. The following configuration will rewrite http://localhost/application.aspx?arg1=abc%5Edef to http://localhost/application?arg1=abc^def:
<rewrite>
<rules>
<rule name="TEST" stopProcessing="true">
<match url="(application.aspx)" />
<action type="Rewrite" url="http://localhost/application?{C:1}^{C:3}" appendQueryString="false" />
<conditions>
<add input="{QUERY_STRING}" pattern="(.*)(%5E)(.*)" />
</conditions>
</rule>
</rules>
</rewrite>
