 In a WP site behind a reverse proxy all was working ok.
 I then set a static home page and all was still working.
 After I set post name permalinks, all pages kept working except home page,
 which had redirect errors.
 After some time spent researching the problem, I found that the problem
 was on line 69 of wp-includes/canonical.php: {{{#!php
 <?php
 $requested_url .= $_SERVER['HTTP_HOST'];
 }}}
 Instead of the value in $_SERVER['HTTP_HOST'], the value in
 $_SERVER['HTTP_X_FORWARDED_HOST'] should be used.
 I wonder if that could be definitively fixed changing line 69 of wp-
 includes/canonical.php with {{{#!php
 <?php
 $requested_url .= isset($_SERVER['HTTP_X_FORWARDED_HOST']) ?
 $_SERVER['HTTP_X_FORWARDED_HOST'] : $_SERVER['HTTP_HOST'];
 }}}
