E.3. An Example

If you find yourself in the position of implementing Cache Digests, you can use the following two tables to verify your code. Table E-2 shows three sample URIs and their MD5 hash values. Table E-3 lists the same three URIs with the bit positions for four hash functions based on the MD5 column in Table E-2. This example uses a MASK_SIZE of 625,000 bytes, or 5,000,000 bits.
