| fry·ing pan (frī'ĭng)
n. A shallow, long-handled pan used for frying food. Also called skillet; also called regionally fry pan, spider. The terms frying pan and skillet are now virtually interchangeable, but there was a time when they were so regional as to be distinct dialect markers. Frying pan and the shortened version fry pan were once New England terms; frying pan is now in general use, as is the less common fry pan, now heard in the Atlantic states, the South, and the West, as well as New England. Skillet seems to have been confined to the Midland section of the country, including the Upper South. Its use is still concentrated there, but it is no longer used in that area alone, probably because of the national marketing of skillet dinner mixes. The term spider, originally denoting a type of frying pan that had long legs to hold it up over the coals, spread from New England westward to the Upper Northern states and down the coast to the South Atlantic states. It is still well known in both these regions, although it is now considered old-fashioned. See Note at andiron. |

spider 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
Spi"der\, n.[OE. spi[thorn]re, fr. AS. spinnan to spin; -- so named from spinning its web; cf. D. spin a spider, G. spinne, Sw. spindel. Seee Spin.]1. (Zo["o]l.) Any one of numerous species of arachnids comprising the order Araneina. Spiders have the mandibles converted into poison fangs, or falcers. The abdomen is large and not segmented, with two or three pairs of spinnerets near the end, by means of which they spin threads of silk to form cocoons, or nests, to protect their eggs and young. Many species spin also complex webs to entrap the insects upon which they prey. The eyes are usually eight in number (rarely six), and are situated on the back of the cephalothorax. See Illust. under Araneina. Note: Spiders are divided into two principal groups: the Dipneumona, having two lungs: and the Tetrapneumona, having four lungs. See Mygale. The former group includes several tribes; as, the jumping spiders (see Saltigrad[ae]), the wolf spiders, or Citigrad[ae] (see under Wolf), the crab spiders, or Laterigrad[ae] (see under Crab), the garden, or geometric, spiders, or Orbitell[ae] (see under Geometrical, and Garden), and others. See Bird spider, under Bird, Grass spider, under Grass, House spider, under House, Silk spider, under Silk. 2. (Zo["o]l.) Any one of various other arachnids resembling the true spiders, especially certain mites, as the red spider (see under Red). 3.

(Mach.) A skeleton, or frame, having radiating arms or members, often connected by crosspieces; as, a casting forming the hub and spokes to which the rim of a fly wheel or large gear is bolted; the body of a piston head; a frame for strengthening a core or mold for a casting, etc. Spider ant. (Zo["o]l.) Same as Solitary ant, under Solitary. Spider crab (Zo["o]l.), any one of numerous species of maioid crabs having a more or less triangular body and ten long legs. Some of the species grow to great size, as the great Japanese spider crab (Macrocheira Kempferi), measuring sometimes more than fifteen feet across the legs when they are extended. Spider fly (Zo["o]l.), any one of numerous species of parasitic dipterous insects of the family Hippoboscid[ae]. They are mostly destitute of wings, and live among the feathers of birds and the hair of bats. Called also bird tick, and bat tick. Spider hunter (Zo["o]l.), any one of several species of East Indian sunbirds of the genus Arachnothera. Spider lines, filaments of a spider's web crossing the field of vision in optical instruments; -- used for determining the exact position of objects and making delicate measurements. Fine wires, silk fibers, or lines on glass similarly placed, are called spider lines. Spider mite. (Zo["o]l.) (a) Any one of several species of parasitic mites of the genus Argas and allied genera. See Argas. (b) Any one of numerous small mites injurious to plants. Spider monkey (Zo["o]l.), any one of numerous species of South American monkeys of the genus Ateles, having very long legs and a long prehensile tail.

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.
