<p class="MsoPlainText">> Currently I'm using Confluene 6.10.2 behind nginx. I have some pages with the page name including character '>' could not accessible, the error is:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">> But when I access the page bypassing the reverse proxy, it's ok, so it could be a problem in nginx.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">It sounds like the request from the client includes a correctly-encoded string %3E, while the request from nginx includes the decoded character >.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Can you show the location{} block in nginx that handles this request? Perhaps there is something there that caused the decoding, that can be changed.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Possibly you can use something like "tcpdump" to see the actual requests, if the logs do not show the details.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Good luck with it,<o:p></o:p></p>
