A system and method for associating blocks of Web page content with caching properties are provided. The caching properties may include global caching properties for all blocks of a Web page and/or individual caching properties for each individual block of the Web page. The caching properties may be identified within the code of the Web page content itself, such as within meta-tags. Caching properties may also be linked to client device characteristics. Both client device caching and proxy device caching of Web page content may be enabled, such that if a block of Web page content in the client device's cache is invalid, the proxy device's cache is checked for the block of Web page content. Thus, a single Web page may be rendered on a client device using blocks obtained from a local cache, a proxy device's cache, and blocks obtained from a source of the Web page content.
