Agree, it’s hard to overestimate the importance of information – “Master of information, master of situation”. Nowadays, we have everything to become a “master of situation”. We have all needed tools like spiders and parsers that could scrape various data from websites. Today we will consider scraping the Amazon with a web spider equipped with proxy services.
How to handle cookie, user-agent, headers when scraping with JAVA? We’ll use for this a static class ScrapeHelper that easily handles all of this. The class uses Jsoup library methods to fetch from data from server and parse html into DOM document.
Working with a Backconnect proxy service (Oxylab.io) we spent a long time looking for a way to authorize it. Originally we used JSoup to get the web pages’ content. The proxy() method can be used there when setting up the connection, yet it only accepts the host and port, no authentication is possible. One of the options that we found, was the following:
In this post we share with you how to perform web scraping of a JS-rendered website. The tools as seen in the header are JAVA with Selenium library driving headless Chrome instances (download driver) and JSoup as parser to fetch data of the acquired HTML.
In this post we want to share with you a new useful JAVA library that helps to crawl and scrape Linkedin companies. Get business directories scraped!
Handy Web ExtractorHandy Web Extractor is a simple tool for everyday web content monitoring. It will periodically download the web page, extract the necessary content and display it in the window on your desktop. One may consider it as the data extraction software, taking its own nitch in the scraping software and plugins.
It’s totally free and available for download.
In this post I want to let you how I’ve managed to complete the challenge of scraping a site with Google Apps Script (GAS).

Getting precise and localized data is becoming difficult. Advanced proxy networks are the only thing that is keeping some companies running intense data gathering operations.
Residential proxies are in extremely high demand, and there are only a few networks available that can offer millions of IP addresses around the world.
Smartproxy is one of those networks, rapidly growing to offer the best product in residential and data center proxies.
Last month a legal case took place in a US court where four professors plus a media organization sued the US Government. The District Court for the District of Columbia conclusion stated that moderate scraping, even when against ToS, is legal.
