<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In one of our deployments, we need to set up an nginx server behind a forward proxy.<o:p></o:p></p>
<p class="MsoNormal">We need to have nginx issue the upstream requests using absolute URLs, e.g.:<o:p></o:p></p>
<p class="MsoNormal">GET http://domain/uri HTTP/1.1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We tried to use a configuration that looks like:<o:p></o:p></p>
<p class="MsoNormal">location ~ ^/proxy/(.*) {<o:p></o:p></p>
<p class="MsoNormal"> proxy_pass $scheme://proxy-ip:proxy-port/$scheme://$1$is_args$args;<o:p></o:p></p>
<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But the problem is that there’s no way to prevent the upstream request uri from starting with /<o:p></o:p></p>
<p class="MsoNormal">(we get /http://domain/uri instead of http://domain/uri)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to submit a patch to support this flow, two options I can think of:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]><span dir="LTR"></span>Add a new parameter proxy_uri that will accept nginx variables, and will take priority<br>
over the existing logic for determining the uri<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]><span dir="LTR"></span>Add a dedicated flag for stripping the /, e.g. proxy_strip_uri_slash on/off<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pros/cons as I see it - #1 seems quite flexible and may enable additional use cases that I can’t<br>
think of right now. The cons of #1 is that there is some duplication between this directive and<br>
proxy_pass (it enables the user to set both, but only one will apply)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please let me whether this change makes sense, and which option you think is better<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
