I have a WordPress blog running on nginx+php+mysql platform, on which I run into a problem related to nginx as a reverse proxy. When I tried to visit <a href="http://www.domain.com/wp-admin/">http://www.domain.com/wp-admin/</a>, it would be redirected to <a href="http://www.domain.com/wp-login.php?redirect_to=http://backend/wp-admin/">http://www.domain.com/wp-login.php?redirect_to=http://backend/wp-admin/</a> instead of <a href="http://www.domain.com/wp-login.php?redirect_to=http://www.domain.com/wp-admin/">http://www.domain.com/wp-login.php?redirect_to=http://www.domain.com/wp-admin/</a>. That&#39;s to say, the word &quot;backend&quot; in the uri wasn&#39;t interpreted to &quot;<a href="http://www.domain.com">www.domain.com</a>&quot;. Except this problem, everything seems to go very well. Now what shoul I do?<div>
