spider
     
         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
   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.
