157	Installation fails on step5 when http to https redirect is active	ck@…	somebody	"The installation procedure fails at step 5 when the virtual host is configured to redirect to https. Example:

{{{
<VirtualHost *:80>
ServerName myshop.example.com
Redirect / https://myshop.example.com...
</VirtualHost>
}}}
{{{
<VirtualHost *:443>
ServerName myshop.example.com
DocumentRoot ...
...
</VirtualHost>
}}}
Reason for this is, that install_step5 is looking for the robots.txt on http only, even when SSL was selected. See the log:

}}}
Note the return code ""302"" of robots.txt.

As soon as I disabled the automatic redirect (by using a ""normal"" http virtualhost), the setup ran through (even when the installer was launched over https):

{{{

}}}
Note the return code is now 200.

This whole checking for the robots.txt needs to be improved as there are also issues when IPv6 is enabled but no vhost configured (see http://www.modified-shop.org/forum/index.php?topic=24162.0)"	Bug/Fehler	closed	normal	modified-shop-2.0.0.0	Installer	1.06	fixed
