uwsgi_hide_header
The `uwsgi_hide_header` directive removes specific headers returned from uWSGI responses.
Description
The uwsgi_hide_header directive is designed to enhance security and customize the headers that are sent back to clients in responses from uWSGI applications. When this directive is present in the configuration, it explicitly specifies headers that should be omitted when the response is generated. This can be particularly useful for preventing the revealing of sensitive information or application details which headers may typically convey.
This directive can be placed in various contexts including http, server, and location, which allows for flexible configurations depending on your application needs. It accepts one argument: the name of the header you want to hide. For example, if you wish to suppress the X-Powered-By header, you would use uwsgi_hide_header X-Powered-By;. The directive effectively integrates into the NGINX processing of requests and responses, intercepting the headers during the response generation process to ensure they do not make it to the client.
Keep in mind that improper use of this directive could lead to an incomplete response context, where some important headers might be required by the client application or intermediaries. Thus, it should be used judiciously, mainly for headers that are verified to contain extraneous data that does not impact overall functionality.
Config Example
server {
location /api {
uwsgi_pass 127.0.0.1:8000;
uwsgi_hide_header X-Powered-By;
}
}Hiding essential headers may lead to unexpected behavior in client applications.
Ensure that you only hide headers that do not impact your application's functionality.
