Reverse Proxy using Rewrite Maps

Question

User-965846884 posted

 I have basic reverse proxys working but I would like to use Rewrite Maps as I potentially have many static pairs that I need to match, not conforming to a standard necessarily.

Currently I have the following rule.

 <rewrite>
            <rules>
                <clear />
                <rule name="ReverseProxy">
                    <match url=".*" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{StaticMap:{Request_URI}}" pattern="(.+)" />
                    </conditions>
                    <action type="Rewrite" url="http://172.28.75.31:90{C:0}" />
                </rule>
            </rules>
            <rewriteMaps>
                <rewriteMap name="StaticMap" defaultValue="/server/">
                    <add key="/server/xhtml/user/fi54321" value="/54321" />
                    <add key="/server/xhtml/user/fi12345" value="/12345" />
                </rewriteMap>
            </rewriteMaps>
        </rewrite>

 

So basically I want  http://mydomain.com/54321 to get rewritten to http://172.28.75.31:90/server/xhtml/user/fi54321

When I enter  http://mydomain.com/54321 I get a 404. After putting in the defaultValue for the rewriteMap it hits that /server/ folder so it appears neither of the two map items actually matches.

Your rewriteMap should look like this

 <rewriteMap name="StaticMap" defaultValue="/server/">
    <add key="54321" value="/server/xhtml/user/fi54321" />
    <add key="12345" value="/server/xhtml/user/fi12345" />
</rewriteMap>

 That gets me a little further I think but once I flipped the key value pairs and enter http://domain.com/12345 it actuall redirected me to http://domain.com/server/xhtml/user/fi12345 showing me them the "defaultValue" page.

If I change
<action type="Rewrite" url="http://172.28.75.31:90{C:0}" />
to
<action type="Rewrite" url="http://172.28.75.31:90{C:1}" />

IIS responds with a 502 error.

Since you say you have basic reverse proxy working, I assume that you have ARR installed and configured.  Can you collect failed request trace log with the new rules?

I do not see it in my inbox - when did you send it and what is the e-mail address from which you sent it?
