Apache mod_disk_cache stores client authentication credentials on disk

[Behrooz_Ice]

mod_disk_cache stores all client authentication credentials for cached objects on disk. This means ***** authentication credentials as well as in certain RFC2616 defined cases standard authentication credentials. In case of Basic Authentication *plaintext passwords* are stored on disk. From modules/experimental/mod_disk_cache.c, function write_headers(), line 641 of apache 2.0.48 or line 598 of apache 2.0.49 Enjoy!
