ARR proxy rule issue - iis

Question

I need to create proxy rewrite in IIS using ARR
So:
I have 2 servers:
https://server1.com
https://server2.com
Now in each of them i have virtual folder
https://server1.com
FilesFolder
https://server2.com
FilesFolder
I saved files in server2
like:
https://server2.com
FilesFolder
users-profile
test.png
Now i need when i open chrome
https://server1.com/FilesFoler/users-profile/test.png
I want that this request go to
https://server2.com/FilesFoler/users-profile/test.png
Now I did proxy rule for Server 1:
Test 1:
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="https://server2/{C:0}" />
<conditions>
<add input="{URL}" pattern="/users-profile/.*" />
</conditions>
</rule>
</rules>
This rule not work if i open url like:
https://server1.com/FilesFoler/users-profile/test.png
But work wjen I open:
https://server1.com/FilesFoler/FilesFoler/users-profile/test.png
Then i try another rule;
Test 2
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="https://server2/FilesFolder/{C:0}" />
<conditions>
<add input="{URL}" pattern="/users-profile/.*" />
</conditions>
</rule>
</rules>
But when I open https://server1.com/FilesFoler/users-profile/test.png
This still not work.....
What wrong here?

Answer 1

In this case, if your request is https://server1.com/FilesFoler/users-profile/test.png.
When IIS handle the condition pattern <add input="{URL}" pattern="/users-profile/.*" />.
Then your {C:0} should be users-profile/test.png.
So the request will be rewritten to
https://server2/users-profile/test.png
instead of
https://server2.com/FilesFoler/users-profile/test.png.
So please replace [C:0} to {R:1} or {R：0}
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="https://server2/{R:0}" />
<conditions>
<add input="{URL}" pattern="/users-profile/.*" />
</conditions>
</rule>
Since you are not using ssl-offloading for server2. Please ensure server2 is using a trusted certificate, otherwise, SSL handshake between ARR and Server2 may fail.
If you get 404 error, please remember to enable Proxy setting in IIS manager->server node->application request routing cache-> Enable proxy.
