X-Turbo-Charged-By

When an OpenLiteSpeed server answers a request that arrived through a trusted proxy such as Cloudflare, the X-Turbo-Charged-By unofficial response header appears as a branding indicator naming the server software.

Usage

OpenLiteSpeed adds the X-Turbo-Charged-By header to responses when the request reaches the server from behind a trusted proxy, a common setup with Cloudflare in front of the origin. LiteSpeed publishes no documentation for the header. Community reports tie the header to OpenLiteSpeed deployments behind a proxy, with the value naming the LiteSpeed engine rather than reflecting caching activity.

The header acts as a server branding indicator, similar to the Server header but specific to LiteSpeed-powered hosting stacks. Administrators concerned about exposing server details remove the header through the server's Server Signature setting or a reverse proxy using proxy_hide_header.

Values

LiteSpeed

The only known value is LiteSpeed, naming the server software family that generated the response.

Example

A response from an OpenLiteSpeed server running behind a proxy includes this header. The value LiteSpeed names the server software.

X-Turbo-Charged-By: LiteSpeed

A typical response from a LiteSpeed-powered hosting stack includes several related headers. The Server header names the server software, X-LiteSpeed-Cache reports the caching layer's outcome, and X-Turbo-Charged-By adds the branding signature.

Server: LiteSpeed
X-Turbo-Charged-By: LiteSpeed
X-LiteSpeed-Cache: hit
