Further to my request yesterday... I would prefer to be able to just generate the md5 hash manually, rather than writing code to use storeKeyPublic() in src/store_key_md5.c. However, I must not be interpreting that function correctly as my hashes do not match the hashes produced in store.log: For example, for 'GET http://www.squid-cache.org/Images/img8.gif' - putting 001http://www.squid-cache.org/Images/img8.gif into the hash generator gives d5bf8db92c34e66592faa82454b5d867, but store.log shows:F506597929DF2C9F8E51ED12E77E6548 Is there a simple way to produce the correct hash without touching the sourcecode? I am very new to this. John Redford. _________________________________________________________________ Get Hotmail on your mobile from Vodafone http://clk.atdmt.com/UKM/go/107571435/direct/01/
