HttpRetriever_​Proxy_​Server

Palladian_HttpRetriever_Proxy_Server

This workflow scrapes a list of current public HTTP proxies www.proxynova.com and then for each proxy server makes a test request to icanhazip.com to check whether the proxy is working fine.

Requires Palladian 2.4+, where the HTTP Retriever’s node dialog has a tab “Proxy”. The setting there overrides the system’s or KNIME’s default proxy settings.
