Check if a request to iis 5 has been arrived - iis

I have two servers on the same internal network the first server that has the role of a client makes HTTP requests to a web service that resides in the second server. The second server has IIS 5 to response in client requests. I have occasionally requests to the web services that has no response at all. How can I find in the IIS 5 if a specific request has been arrived in the IIS? I have to find if there is connectivity problem (network issues) or IIS or maybe application (web service) issues
Thanks

Hosting outofprocess 3.1 web app require Windows Server Hosting updated too?

I am trying to understand the difference between inProcess and outofprocess while trying to host a dot net core app on IIS. If I am hosting outofprocess, does it still require updated .net core server hosting, or installed at all?
Whether you are using in-process or out-of-process, you need to use .net core server hosting. Host
On startup, an ASP.NET Core app builds a host. The host encapsulates all of the app's resources, such as: 1. An HTTP server implementation 2. Middleware components 3. Logging 4. Dependency injection (DI) services 5.Configuration
In process hosting model
A request arrives from the web to the kernel-mode HTTP.sys driver.
The driver routes the native request to IIS on the website's
configured port, usually 80 (HTTP) or 443 (HTTPS).
The ASP.NET Core Module receives the native request and passes it to
IIS HTTP Server (IISHttpServer). IIS HTTP Server is an in-process
server implementation for IIS that converts the request from native
to managed.
After the IIS HTTP Server processes the request:
The request is sent to the ASP.NET Core middleware pipeline.
The middleware pipeline handles the request and passes it on as an
HttpContext instance to the app's logic.
The app's response is passed back to IIS through IIS HTTP Server.
IIS sends the response to the client that initiated the request.
Out-of-process hosting model
Requests arrive from the web to the kernel-mode HTTP.sys driver.
The driver routes the requests to IIS on the website's configured
port. The configured port is usually 80 (HTTP) or 443 (HTTPS).
The module forwards the requests to Kestrel on a random port for the
app. The random port isn't 80 or 443.

Redirecting HTTPS call to a .NET Core Web API with IIS and Kestrel

hopefully someone can help me.
This is the scenario I want to implement:
Server A has IIS installed and hosts a web app "mysite.com" and some web apis.
Server B has a .NET Core Web API hosted as a Windows Service.
When a client makes a request to a specific port like "mysite.com:9091/api/get-value"
I would like for IIS to re-route that call with same payload to server B on "myapi:9091/api/get-value" through HTTP.
The reason I want to do this is because We have authentication and certificates already configured on Server A, and also we want all incoming requests to go through the main site.
I have been reading on reverse proxy with IIS, and it would seem to be what I need, but it's not clear if the hosted app that will be running under Kestrel must be on the same physical machine as the IIS Web Server (i.e. Server A), or I can re-route to whichever other server I want, as long as it's on same network.
Any thoughts will be appreciated.
Hopefully my question is clear enough, otherwise please do let me know and I'll try to rephrase.
It is not necesarray to have both kestrel and iis on same server.
You could use the iis URL rewrite rule and reverse proxy to forward the request to the Kestrel server:

502 - web server received an invalid response while acting as a gateway or proxy server. IIS

I have 2 servers (Web & APP Server).
I have hosted my API's on APP Server & APP server is accessed by ARR from Web Server using reverse proxy.
The error is displayed exactly at 2 min after calling the API.
I have increased the time limit in IIS as well.
I updated the timeout in the Application request Routing of Reverse Proxy Server and this resolved my issue.

How does an azure app service access a no azure web server

I have an Azure app service and in some cases I need to send a web request to a non-azure webserver. What do I need to do to make it possible.
Currently the web request fails with no clear error message.
In response to a HttpClient Put request I get a System.Net.WebException exception which says there were errors.
THe same request works from a desktop application.
If your webserver is reachable from the internet you should be able to access it through your App Service. Try to log a ping to your webserver and google (8.8.8.8).
If your App Service is in a VNET you should enable some outbound rules to your webservers IP adress.
The server I am connecting to is an other Azure service. After some more investigating, It appears that I can connect to it if I do not use SSL (i.e. http://) but the connection is immediately closed when using SSL (https://). I assume that the problem must be related to the use of SSL.

IIS 7.5 Reverse Proxy Implementation

I am curious to understand how IIS 7.5 Reverse Proxy is implemented in Rewrite Module (v2).
I am planning to setup a website that will handle proxing between requests coming from users (internet) and my HTTP services that are deployed on the same server. I have setup a website within IIS and configured the reverse proxy logic. I've then setup another website on the same server and deployed all my WCF REST services there. I am planning to implement IIS offloading, common tasks (such as authentication, etc) on the reverse proxy website before the request gets to the actual services (like WCF routing service for SOAP). Configuration is working perfectly fine.
However I am trying to understand the implications of this setup. When IIS does reverse proxing, does it create a new HTTP request (and a new TCP port) between those two websites? And even if both sites are on the same server? Should I expect number of TCP connections opened on this server to get doubled when reverse proxy is used?
Furthermore, has anyone experienced any performance/resource issues with a similar setup?
Cheers,
OS
