Hi,
Currently… The posts are coming from the same computer that is hosting NGINX that passes the requests to an external server.
Eventually… NGINX will be run on the same computer with Apache and will also function as a load balancer for multiple servers. One being the same as NGINX and other external servers.
The posts are from a custom poster process that is an .EXE run from the windows command prompt or a process that calls the POSTER executable.
C:\POSTER> Poster h:http://localhost/cr-bin/mp.exe f:test.txt
h: is the host to send to
f: is the file with the payload to be sent to the final destination which is the mp.exe on the server listed in the proxy_pass parameter.
Everything looks to work as it should. But the ‘gmer3.itd.sterling.com/home.htm’ Log entries are just not what I expect to see.
I am installing NGINX to rate limit a customer that is sending multiple posts so fast that we occasionally miss one, and hope this will resolve that.
Again, the proxy redirect is working, just the log entries is what prompted my asking.
Thanks,
- Benn

Benn,
I guess my explanation wasn't clear enough, so I'll try again.
That value is not coming from anywhere in your server's configuration - it has nothing to do with proxy_pass or anything else. It is the value of the "Referer" header that is in the incoming request.
First, are these log lines from requests that you are making to the server yourself, or are they coming from someone else?
If it is your own traffic, where are you making your requests from? Is it a page in a web browser, or is it some other tool?
If it is a web browser, that is usually the URL of the web page that is open in the browser. For example, if I have a website at `example.com/page.html`https://url.emailprotection.link/?bDBb9TVOKiqDPh_SUvfalWM90G6wcWScPnK_EVq6xVxh-Jq5ndDGgvfcC5U_tqxpluRe5jF35zSgN416HI1RIHw~~ with a form on it that submits to your server, the value in that place in the logs will be `https://example.com/page.html`https://url.emailprotection.link/?bMe1AJs-bSscT1yazCR9XS0kzX52Qa1-DwoIBV-QK8xxhHB1slVsgthl_uC3ltg7Vu05wQoXQi9lo9go4OQWCbA~~ so that your server can see where the request came from.

Hello Moshe,
Thanks for the reply. I guess I was not clear enough in my post. I know the /cr-bin/mp.exe is part of the POST request.
What I do not understand is where the gmer3.itd.sterling.com/home.htmhttps://url.emailprotection.link/?bD5H3QzZ3V5r-EeQ1owgpRQF9oV5l2NRIm985JaimcuSK9Ouf7HkyYPBjb_5XEDTDFQOhTH2rYvU2h1CLfmBEfM8_cgt7-mqSW8-5oZbZzhsOjFEa1jMAMRarOyYb8wct is coming from. It is not my proxy_pass value.
It is not part of the POST request or part of the nginx proxy_pass or any thing I can find in my configuration.
Is my post being sent to both my proxy_pass value and this site in the log? Do I have a hacked nginx?

Benn,
That part of the log is not the request URL, it is the referrer header. The path that was requested on your server is before that - a POST request to "/cr-bin/mp.exe". The referrer (which the HTTP standard actually misspells as "referer") is the web page that is making this request to your server.

Hello,
I have just installed the NGINX service to help rate limit connections to my Apache server on Windows.
NGNIX 1.19.10 on Windows 10 64 bit
Everything seems to be working fine but I am getting access log entries that I do not understand for the pages I am redirecting.
I am running a process that posts to the server. NGNIX is processing the request and passing it to the destination server but it is not gmer3.itd.sterling.com/home.htmhttps://url.emailprotection.link/?bD5H3QzZ3V5r-EeQ1owgpRQF9oV5l2NRIm985JaimcuSK9Ouf7HkyYPBjb_5XEDTDFQOhTH2rYvU2h1CLfmBEfM8_cgt7-mqSW8-5oZbZzhsOjFEa1jMAMRarOyYb8wct as shown in the access log entries below.
Any Idea why
