# Remove response headers

Remove from response all headers that start with a certain name.

JavaScript

```
export default {  async fetch(request) {    // Define the prefix of the headers you want to remove    const headerPrefix = "x-header-";
    // Receive response from the origin    const response = await fetch(request);
    // Create a new Headers object to modify response headers    const newHeaders = new Headers(response.headers);
    // Remove headers that start with the specified prefix    for (const [key] of newHeaders.entries()) {      if (key.startsWith(headerPrefix)) {        newHeaders.delete(key);      }    }
    // Return the modified response with updated headers    return new Response(response.body, {      status: response.status,      headers: newHeaders,    });  },};
```
