[squid-users] Users Guide --- Dead link

[Laurence Finston]

Hello,

I'm just starting out learning about Squid.  The link to the Squid Users Guide 
by Oskar Pearson on http://www.squid-cache.org/Doc/ is dead:

404 Not Found

    Code: NoSuchBucket
    Message: The specified bucket does not exist
    BucketName: deckle-redirects
    RequestId: 317BF36686DE608E
    HostId: hE+eXv0FqL0/9aB66vz0NV1YjtNp4Cc/hYplqLRaF+CuiELrShKSoaE8xhe3URcl3+5baEosyM8=

Could somebody repair it or let me know where I could find the document?

Thank you.

Laurence Finston
