ACHE is a focused web crawler. It collects web pages that satisfy some specific criteria, e.g., pages that belong to a given domain or that contain a user-specified pattern. ACHE differs from generic crawlers in sense that it uses page classifiers to distinguish between relevant and irrelevant pages in a given domain. A page classifier can be defined as a simple regular expression (e.g., that matches every page that contains a specific word) or a machine-learning-based classification model....

...Many of the cases explore techniques related to request analysis, signature generation, and reverse engineering that are often needed when interacting with modern web applications. It also provides supplementary materials and tools used in crawling workflows, such as debugging utilities and reverse-engineering aids.

...It is designed to make crawler development straightforward by allowing developers to extract page elements using jQuery-style selectors rather than complex parsing logic. It integrates several well-known Java libraries and frameworks, including tools for HTTP requests, HTML parsing, JSON processing, and application development. Through its annotation-based design, developers can define crawling rules and data extraction logic directly within Java classes, reducing boilerplate code and improving readability. Gecco also provides mechanisms for handling dynamic web content, including support for asynchronous requests and extraction of JavaScript variables from pages. ...
