Rendering a meta-page through a meta-engine, the meta-engine including a tag handler, the meta-page including static content, JSP dynamic content and one or more types of non-JSP dynamic content, and identifications of shared variables. Embodiments include writing to output the static content of the meta-page, rendering the JSP dynamic content to the output of the meta-engine, and inserting into the non-JSP dynamic content additional non-JSP dynamic content identifying current values of shared variables. Embodiments include rendering the non-JSP dynamic content through dynamic server page engines, including passing current values of shared variables to the dynamic server page engines, reading from the non-JSP additional dynamic content as rendered the current values of shared variables, deleting from the non-JSP dynamic content as rendered the additional non-JSP dynamic content as rendered, and writing the non-JSP dynamic content as rendered, at its location among the static content, to the output of the meta-engine.
