Behavior Change

lighttpd now performs strict URL parsing and normalization on HTTP requests. This is configurable, but the defaults are now strict unless explicitly configured otherwise.

Enabling strict URL parsing and normalization by default provides more consistent behavior for mod_redirect and mod_rewrite, which match against the (url-encoded) URL request. However, decoding %2F by default, while generally desirable for consistency, is potentially a breaking change for those encoding URLs in the url-path and relying on the literal ‘/’ as a delimiter. For those uses, “url-path-2f-decode” => “disable” will need to be explicitly set in the lighttpd config.

https://redmine.lighttpd.net/projects/lighttpd/wiki/Server_http-parseoptsDetails

The recommended settings for server.http-parseopts are the following, unless specific use requires looser settings:

server.http-parseopts = (
        "header-strict"            => "enable",
        "host-strict"              => "enable",
        "host-normalize"           => "enable",
        "url-normalize"            => "enable",
        "url-normalize-unreserved" => "enable",
        "url-normalize-required"   => "enable",
        "url-ctrls-reject"         => "enable",
        "url-path-2f-decode"       => "enable",
        "url-path-dotseg-remove"   => "enable",
        "url-query-20-plus"        => "enable"
      )
