CACHING DYNAMIC CONTENTS AND USING A REPLACEMENT OPERATION TO REDUCE THE CREATION/DELETION TIME ASSOCIATED WITH HTML ELEMENTS

An event to delete a structured object of a Web page rendered in a browser can be detected. The structured object comprises an HTML element set that was dynamically created for the Web page. The structured object can be placed in a cache without deleting memory allocations for the structured object. An event to dynamically create a new object of the Web page can be detected. The cache can be queried to find an object with structure equivalent to that of the new object. The found object can be taken from the cache and used as the new object after content of the cached object is replaced with that needed for the new object. Memory allocation and deallocation costs that would otherwise be needed to dispose of a dynamic HTML element set and to create a new HTML element set are thus saved using the cache.
