Template detection technique is important for many applications. Most template detection methods utilize content repetition as a hint to detect template blocks that lots of web pages are required as input. So they usually process web pages in batches that a newly crawled page can not be processed until enough pages are collected. This consumes large storage consumption to cache web pages and results in a huge delay in data refreshing. In this paper, we present an incremental framework to detect templates in which a page is processed as soon as it has been crawled. Under this framework, we don't need to cache any web page. Experiments show that our framework consumes less than 7% storage than traditional methods. And also the delay of data refreshing induced by the batch process is completely eliminated.
