I want to use IIS8 to route traffic from ports 80/443 to two applications running on the same server - one sitting on port 8080 (node.js app, running as a separate service), another on port 8090 (a .NET application, running on the same IIS, handling api calls).
I have setup an app on port 80, with the following web.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="rewrite api to backend calls" stopProcessing="true">
<match url="^api/(.+)$"/>
<action type="Rewrite" url="http://127.0.0.1:8080/{R:1}"/>
</rule>
<rule name="rewrite everything else to frontend" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://127.0.0.1:8090/{R:1}"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
Unfortunately this approach doesn't work - whatever resource I try to query, I get 404 error.
In the FREB logs, requests are properly translated from OldUrl, to the NewUrl, nothing is found in cache and then the following is mentioned in logs as MODULE_SET_RESPONSE_ERROR_STATUS
ModuleName="IIS Web Core", Notification="MAP_REQUEST_HANDLER", HttpStatus="404", HttpReason="Not Found", HttpSubStatus="4", ErrorCode="The filename, directory name, or volume label syntax is incorrect.
(0x8007007b)", ConfigExceptionInfo=""
Proxy in Application Request Routing had to be enabled as per the IIS Rewrite not working (but redirection does) topic. Issue solved :)

I'm trying to deploy my nodejs api on IIS by reverse proxy method but getting error:
HTTP Error 400.605 - Bad Request
The request cannot be routed because it has reached the Max-Forwards limit. The server may be self-referencing itself in request routing topology.
The steps i have followed:
1- Created new website on IIS
2- Added a new rule with reverse proxy(Added my hostname i.e localhost:8099 for now)
3- Installed pm2 to running my website constantly
my web.config after rewrite rule:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://localhost:8099/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
So you mean that you access the new site through port 8099 and its proxy rule forward request to http://localhost:8099/{R:1} ?
If so, please change the binding of the site to other port,or add another binding for it but not use 8099 port, or the target url of proxy rule to other port.
This error is caused by original request and forward request both request for 8099 port.
I want to know if anybody here can help. I have using Nest.js for my program and I have added some web socket code into my program for some new feature. However, when I deploy to the server and there are a problem to the IIS Setting.
Now I use URL rewrite for my http server. My HTTP server run on port 8200 in localhost. My web socket port is 8085. What I have tested is that I can call it in local using ws://localhost:8085/socket.io/?EIO=3&transport=websocket and also ws://192.168.X.X:8085/socket.io/?EIO=3&transport=websocket in internal network. However, I cannot call by ws://myurl.com/socket.io/?EIO=3&transport=websocket. The URL is binding with a IIS server. Below is my IIS server web.config. Is it because we socket cannot called by url? or is my web.config have something wrong? Can anybody help me?
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="WebSocketsReverseProxy" enabled="true" stopProcessing="true">
<match url="ws://(.*)"/>
<action type="Rewrite" url="ws://localhost:8085/{R:1}"/>
</rule>
<rule name="HttpsReverseProxy" stopProcessing="true">
<match url="(.*)"/>
<conditions>
<add input="{CACHE_URL}" pattern="^(https?)://"/>
</conditions>
<action type="Rewrite" url="http://localhost:8200/{R:1}"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
remove ws:// from the first rule. iis match rule only matches folder or file but does not match the domain name. if you want to match the domain use condition server variable {HTTP_HOST}.
I'm currently trying to set up a Gitea server on my Windows server 2016 standard server with Plesk installed. I have a subdomain setup which is git.thetofushop.net and I'm trying to make a Reverse proxy to point to the Gitea server which runs on port 3000.
this is my web.config for the subdomain
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="ReverseProxyInboundRule1" stopProcessing="true">
<match url="(.*)" />
<action type="Rewrite" url="http://149.56.184.96:3000/{R:1}" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
But this only works internally on the server itself, it is not working outside of the server. You can visit the IP and port, but the reverse proxy point blank refuses to work. Now I'm not super adept with IIS, but I've tried what I can figure out from what I've found. If someone can give me a reason and an exact steps to fix this id. I am also open at this point to allowing someone to TeamViewer in and fix it as I've been trying to figure this out for 8 straight hours.
Thanks in advance
On my development machine, I am trying to configure IIS as a reverse proxy to forward requests coming in port 443 to a nodejs application running locally.
The requests are getting forwarded fine, but sometimes the the nodejs application tries to redirect the browser to an external site and the IIS url rewrite module change that also to point to the local server.
I am accessing the site using https://localhost/test
IIS reroutes the requests to the node app http://localhost:14819/test
The node app returns an http 302 with location header set to https://example.com/someroute
IIS transforms this to https://localhost/someroute
I want the external urls to be untouched by IIS. How to do this?
Here is my Web.config content
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<clear />
<rule name="ReverseProxyInboundRule1" patternSyntax="ECMAScript" stopProcessing="true">
<match url="^test(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" pattern="^localhost" />
</conditions>
<action type="Rewrite" url="http://localhost:14819/test{R:1}" logRewrittenUrl="true" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
If you have any redirect coming back from the backend proxy and you do
not want to redirect the Location header coming ,You can do that by
unchecking "Reverse rewritehost in response headers" in Application
Request Routing
Select the server node in IIS manager
Go to Application Request routing Cache
Click on Server proxy Settings
UnCheck "Reverse rewritehost in response headers"
A server (x.com) has the following parameters:
- It is accessible from the outside from port 80.
- It has an internal service running on port 1000.
- The service needs to be accessible from a subdomain (service.x.com)
Running IIS on Windows 10, I did the following:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="URL Rewrite" enabled="true" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{CACHE_URL}" pattern="^(https?)://" />
</conditions>
<action type="Rewrite" url="{C:1}://localhost:1000/{R:1}" logRewrittenUrl="true" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
And it worked beautifully.
The same code, on the other end, run on Windows Server 2012 R2 yields this:
HTTP Error 404.4 - Not Found
The resource you are looking for does not have a handler associated with it.
Module IIS Web Core
Notification MapRequestHandler
Handler ExtensionlessUrlHandler-Integrated-4.0
Error Code 0x8007007b
I do not understand why it works on one version of IIS and not on the other one.
I found: ARR (Application Request Routing) needs to be enable.
Of course, this is not mentioned anywhere in any of the error messages nor in log.
