World-Wide Web
(Or "robot", "crawler") A program that automatically explores the World-Wide Web by retrieving a document and recursively retrieving some or all the documents that are referenced in it. This is in contrast with a normal web browser operated by a human that doesn't automatically follow links other than inline images and URL redirection.
The algorithm used to pick which references to follow strongly depends on the program's purpose. Index-building spiders usually retrieve a significant proportion of the references. The other extreme is spiders that try to validate the references in a set of documents; these usually do not retrieve any of the links apart from redirections.
The standard for robot exclusion is designed to avoid some problems with spiders.
Early examples were Lycos and WebCrawler.

Spider definition

The trust of the hypocrite is compared to the spider's web or house (Job 8:14). It is said of the wicked by Isaiah that they "weave the spider's web" (59:5), i.e., their works and designs are, like the spider's web, vain and useless. The Hebrew word here used is _'akkabish_, "a swift weaver." In Prov. 30:28 a different Hebrew word (semamith) is used. It is rendered in the Vulgate by stellio, and in the Revised Version by "lizard." It may, however, represent the spider, of which there are, it is said, about seven hundred species in Palestine.
