IIS Rewrite Multiple URLS to Ports

Solution 1:

Something like this (in your web.config) should work:

<rule name="solution1" stopProcessing="true">
    <match url="^(solution1/)(.*)" />
    <action type="Rewrite" url="http://localhost:8888/{R:2}" />
</rule>
<rule name="solution2" stopProcessing="true">
    <match url="^(solution2/)(.*)" />
    <action type="Rewrite" url="http://localhost:8890/{R:2}" />
</rule>

IIRC, the {R:0} will match the entire URL, so you don't want that in this case. Instead, with the ( and ) you define 'capturing groups'; {R:2} will be everything after solution1/ or solution2/.

_{If you're set on using the IIS GUI, I hope you'll be able to find the fields that need to be filled; they are the same ones you already use, only with different parameters.}
