Nginx Set Cookie No Httponly Secure

Introduction to Cookies and Nginx

Cookies are small text files that are stored on a user’s computer via a web browser. They are used to store information related to a user’s web browsing session and are often used to collect user data such as preferences and website visited. Nginx is a popular web server software that is commonly used to host websites and web applications. It is also used to secure data, control user access, and speed up web requests.

Nginx offers a number of features to help secure its users data. One of these is the ability to add a HTTPOnly and Secure flag to cookies. This ensures that any cookies set by Nginx are not accessible to malicious JavaScript code and can only be accessed by the web server that created them.

What is an Httponly Cookie?

An Httponly cookie is an type of cookie that is only accessible via an http request. This means that a web application can set an Httponly cookie, but any requests made to access the cookie will be rejected if it does not originate from the same web server. The Httponly flag is used to protect Cookies from being accessed by malicious scripts that could be used to steal user data or compromise web application security.

When the Httponly flag on a Cookie is enabled, any JavaScript code that attempts to access the Cookie will return an error. This makes it less likely that a malicious attacker can gain access to the Cookie and its data.

What is a Secure Cookie?

A Secure Cookie is a type of Cookie that is only accessible over an encrypted connection (HTTPS). This ensures that the Cookie data is protected by the TLS/SSL encryption, making it much more difficult for an attacker to decode the Cookie data. By setting the Secure flag on a Cookie, web application developers can ensure that the data stored in the Cookie is not compromised by an unencrypted connection.

The Secure flag can be used in combination with the Httponly flag for an extra level of security. By setting both flags, web applications can further protect their Cookies from malicious scripts and attempts to steal user data.

How to Set Httponly and Secure Flags for Cookies in Nginx?

Nginx offers a number of configuration options to set the Httponly and Secure Flags for Cookies. First, the Set-Cookie header should be added to each response from Nginx that creates a Cookie. This sets the Httponly and Secure flags for the Cookie, as shown below:


Set-Cookie: my_cookie=value; HttpOnly; Secure;

In addition to setting the flags in the Set-Cookie header, it is also possible to configure Nginx to set the flags for all Cookies created by Nginx. This can be configured by setting the http_cookie and secure_cookie directives, as shown below:


http_cookie HttpOnly;
secure_cookie Secure;

Once these directives have been added to the Nginx configuration file, the Httponly and Secure flags will be set for all Cookies created by Nginx.

Conclusion

Nginx is a powerful and popular web server software that offers a number of features for securing data. One of these features is the ability to set the Httponly and Secure flags for Cookies. This ensures that any Cookies set by Nginx are protected from malicious scripts and attempts to access user data. By setting the http_cookie and secure_cake directives, web applications can ensure that their Cookies are protected from malicious access.
