Description¶

The access module is used to deny access to files.

Options¶

url.access-allow
Allow access only to files with any of given trailing path names. (since 1.4.40)
Default value:empty

url.access-deny
Denies access to all files with any of given trailing path names.
Default value:empty

Usage examples¶

url.access-allow

    url.access-allow = ( ".jpg", ".gif")

You might want to deny access to all files ending with a tilde (~) or .inc because of:

1. Text editors often use a trailing tilde for backup files.
2. And the .inc extension is often used for include files with code.

url.access-deny

    url.access-deny = ( "~", ".inc")

Directory deny access
An empty string in url.access-deny matches all requests

    $HTTP["url"] =~ "^/libraries" {
        url.access-deny = ("")
    }

Note: Creating a very, very large list of conditions is inefficient. If creating conditions from a list, consider batching them with regex alternations into many fewer conditions, each with a large regex. See #3074

Deny bots if User-Agent matches robots.txt
Sample one-liner to generate config:
curl -s https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/robots.txt/robots.txt | perl -e 'while (<>) { /User-agent:\s*(.+)/ && push @x, quotemeta($1); } print "\$HTTP[\"user-agent\"] =~ \"(?i:", join("|",@x), ")\" { url.access-deny = (\"\") }\n"'
