Link discovery from web scripts

A computer-implemented method, a computer system, and computer media for discovering links in scripts are provided. The computer system includes a crawler, a rules engine, and an index that are utilized to store links generated by scripts located in webpages in the index. The crawler traverses a network to locate webpages having scripts. The rules engine parses the located webpages and extracts the scripts based on rules that are satisfied by segments of the extracted scripts. The rules engine evaluates the segments of the extracted scripts to generate links. After the rules engine validates the links, the rules engine transmits the links to the index for storage.
