Andy's questions

In Apache if I make a request that contains multiple Link headers, it will merge them into one comma separated list.

In nginx, if I make the same request all but the last are discarded

For example, with the following request:

PUT https://example.org HTTP/1.1
Link: </some/path>; rel="parent"
Link: </another/path>; rel="child"

Using Apache, the PHP $_SERVER['HTTP_LINK'] variable will contain the following:

</some/path>; rel="parent", </another/path>; rel="child"

However in nginx, the variable will be:

</another/path>; rel="child"

Is there a feature toggle in nginx config I can turn on to mimic Apache's behaviour?

UPDATE:

I should add that I am using PHP-FPM as a fastcgi_pass. I added the following to the nginx config which passes the first Link header instead of the last:

fastcgi_param HTTP_LINK $http_link;

I wonder if there's any way to access $http_link as an array and split it myself in the config file.

I have an Apache 2.4 VirtualHost on an AWS EC2 instance with the following config:

<Directory /srv/www/example.org>
    Require ip [REDACTED] # Office IP
    Require local
</Directory>

When I make a request from the redacted external office IP address it works fine, but when I make a request from the EC2 instance I get a 401 Unauthorized error. I tried replacing Require local with Require ip 127.0.0.1 to no avail.

The only way I am able to make requests from the local machine is to add its external IP address e.g Require ip 123.45.67.89.

I had a look at the access log and all requests made from the local machine are logged as having come from the external IP address rather than 127.0.0.1.

The /etc/resolv.conf file looks like this:

options timeout:2 attempts:5
; generated by /usr/sbin/dhclient-script
search eu-west-2.compute.internal
nameserver 172.31.0.2

Could this be happening because the IP/hostname is being resolved externally by another AWS service?

Can I change any server config so that Apache sees requests from the EC2 instance as being local, so I can use the Require local directive?

I'm trying to restrict access to the wp-login.php file of a wordpress installation to a single IP address using the following .htaccess directive:

<Files wp-login.php>
    order deny,allow
    allow from y.y.y.y # Actual IP address replaced
    deny from all
</Files>

This works but it's also Denying access to wp-login.php files within the /public_html/subdomains directory. I've tried wrapping the Files directive inside a Directory directive like so:

   <Directory />
    Order allow,deny
    <Files wp-login.php>
       Order deny,allow
       allow from y.y.y.y
       deny from all
    </Files>
   </Directory>

But this just gives me a 500 Internal Server Error. I've also tried replacing the / in the Directory match with /public_html to no avail

Is there a way I can get the FilesMatch directive to only match the /public_html/wp-login.php file and not those inside the subdomains directory?
