Evaluation of a Multi-Queue Web Caching Scheme that Differentiates the Content-Type of Documents1

This work presents a caching scheme that differentiates the content-type of the documents and uses a different queue for each of them. In that way, the replacement policy that better performance is achieved for each content-type and cache size can be applied. We evaluate by means of simulation the performance of the LRU, LFU-DA, GDSF and GD * replacement policies in the classical caching scheme with the results obtained with this new scheme using the same replacement policy for each content-type and using a different replacement policy for each content-type
