Chained Proxies

Emmanuel | Last updated: Dec 15, 2020 03:13PM UTC

Dear Portswigger support team, In our network, we need to use corporate proxies to reach internet websites. Using Burp version 5.1 and previous was OK, the browser could reach Internet website through burp and corporate proxies. After Burp 5.1 and until 2020.12, using the same corporate proxies the Internet connection failed. The browser show an error "Failed to connect to [HIDDEN_CORPORATE_IP]:[HIDDEN_CORPORATE_PORT] Corporate proxies use Squid. Do you know an issue about this usage ? Thank-you for your reply, Regards,

Hi Emmanuel, Is your corporate proxy using a particular type of authentication?
