Nginx HTTP Server - Fourth Edition

The = modifier

The requested document URI must match the specified pattern exactly. The pattern here is limited to a simple literal string; you cannot use a regular expression:

server { 
    server_name website.com; 
    location = /abcd { 
    [...] 
    } 
} 

The configuration in the location block:

• Applies to http://website.com/abcd (exact match)
• May apply to http://website.com/ABCD (it is case-sensitive if your operating system uses a case-sensitive filesystem)
• Applies to http://website.com/abcd?param1&param2 (regardless of query string arguments)
• Does not apply to http://website.com/abcd/ (trailing slash)
• Does not apply to http://website.com/abcde (extra characters after the specified pattern)
