The next user to request the site can get the contents from both your machine and the original server. As more people access a page, it becomes available from more machines, reducing the load on the original server.

• TrueCrypt Free open source disk encryption software for Windows 7/Vista/XP/Mac OSX/ & Linux. Creates a virtual encrypted disk within a file and mounts it as a real disk. Encrypts an entire partition or storage device such as USB flash drive or hard drive. Encrypts a partition or drive where Windows is installed (pre-boot authentication). Encryption is automatic, real-time (on-the-fly) and transparent. Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted. Encryption can be hardware-accelerated on modern processors. Provides plausible deniability, in case an adversary forces you to reveal the password: Hidden volume (steganography) and hidden operating system. More information on documentation page
