# Caching Umbraco supports two approaches to caching. Response caching uses HTTP headers to control browser and proxy caching. Website output caching stores the full rendered HTML on the server and skips the Razor pipeline on subsequent requests. * [Response Caching](/umbraco-cms/18.latest/develop-with-umbraco/caching/response-caching.md) - configure `Cache-Control` headers to control how browsers and proxies cache responses. * [Website Output Caching](/umbraco-cms/18.latest/develop-with-umbraco/caching/website-output-caching.md) - enable server-side output caching for Razor-rendered pages to avoid re-executing the rendering pipeline. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.umbraco.com/umbraco-cms/18.latest/develop-with-umbraco/caching.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
