Code before:

			request: this.request,
			site: pipeline.site,
			url,
			get originPathname() {
				return getOriginPathname(renderContext.request);

			get session() {
				if (this.isPrerendered) {
					pipeline.logger.warn(

						`context.session was used when rendering the route ${green(this.routePattern)}, but it is not available on prerendered routes. If you need access to sessions, make sure that the route is server-rendered using \`export const prerender = false;\` or by setting \`output\` to \`"server"\` in your Astro config to make all your routes server-rendered by default.

Review comment (suggestion):
```suggestion
				if (!pipeline.manifest.csp) {
```
You're coercing to boolean and then comparing to false, so it's equivalent to this, which is simpler
