<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Currently… The posts are coming from the same computer that is hosting NGINX that passes the requests to an external server.<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">C:\POSTER> Poster h:http://localhost/cr-bin/mp.exe f:test.txt<o:p></o:p></p>
<p class="MsoNormal">h: is the host to send to<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">Again, the proxy redirect is working, just the log entries is what prompted my asking.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks, <o:p></o:p></p>

<p class="MsoNormal">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.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">First, are these log lines from requests that you are making to the server yourself, or are they coming from someone else?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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 `<a href="https://url.emailprotection.link/?bDBb9TVOKiqDPh_SUvfalWM90G6wcWScPnK_EVq6xVxh-Jq5ndDGgvfcC5U_tqxpluRe5jF35zSgN416HI1RIHw~~">example.com/page.html`</a>
with a form on it that submits to your server, the value in that place in the logs will be `<a href="https://url.emailprotection.link/?bMe1AJs-bSscT1yazCR9XS0kzX52Qa1-DwoIBV-QK8xxhHB1slVsgthl_uC3ltg7Vu05wQoXQi9lo9go4OQWCbA~~">https://example.com/page.html`</a>
so that your server can see where the request came from.<o:p></o:p></p>
