Abstract
A first unclassified uniform resource locator (URL) is received. An originally primary bloom filter is initialized. A second bloom filter is initialized. In response to receiving a 'no match' result from querying the primary bloom filter for the received first unclassified URL, insert operations are performed on both the originally primary bloom filter and the secondary bloom filter. At a time subsequent to inserting the first unclassified URL into both the originally primary and secondary bloom filters, a determination is made that a false positive rate associated with the originally primary bloom filter exceeds a threshold. In response to the determination, the secondary bloom filter is designated as a replacement primary.
