More than just a program that reads HTML and retrieves files, Teleport Exec provides advanced functionality you won't find in any competing program, and won't want to code yourself. Among other things, Teleport Exec
Reads HTML 4.0 and most of the current extension languages, including CSS (Cascading Style Sheets) versions 1.0 and 2.0, and Dynamic HTML (both Netscape and Microsoft versions).
Uses true multithreading to retrieve many files simultaneously, avoiding network bottlenecks.
Monitors the responsiveness of each server it contacts, in order to maximize retrieval speed.
Can rewrite HTML links to produce localized versions of web pages -- no other spider can do this.
Provides inline filter functionality, efficiently limiting both how the spider explores and what it retrieves.
Uses a tuned, high-performance, multithreaded database, enabling the spider to operate with very low CPU and memory requirements.
Has been refined over time to accommodate and understand the many idiosyncrasies of webservers and web page authors.
