The present invention provides a dynamic, easily configurable system, which can be used to encrypt or otherwise hide the internal structure of a network. The present invention protects access to computing systems via a URL by encrypting all or a portion of the URL during the transmission of information over a network. Prior to the actual transmission of the information, fields in the URL can be encrypted using conventional encryption techniques. The encryption will occur after the destination has been determined such that the encryption will not cause the information to be misdirected to a wrong destination. At the destination location, there is first a determination that this URL is an encrypted URL. At this point, a decryption technique is employed based on the predetermined encryption scheme to decrypt the URL. The full URL is now accessed only by the destination location and is not accessible during travel over the network between the originating and destination locations.
