using proxy + HTTPS ends with SSL session is not started yet

[xambroz]

Hello,
there seems to be some issue with (may be race condition of slow non-caching) http proxy when requesting HTTPS sites.

Without proxy

$ whatweb https://www.root.cz/ 
https://www.root.cz/ [200 OK] Cookies[iinfo-sid], Country[CZECH REPUBLIC][CZ], Email[b945dfd40ee14a049221190a7f57fe2d@sentry.iinfo.cz,erik.dvorak@iinfo.cz], Frame, HTML5, HTTPServer[nginx/1.14.2], HttpOnly[iinfo-sid], IP[91.213.160.188], JQuery[2.1.4], Open-Graph-Protocol[article][160071904046461], PasswordField[us_pwd], Script[text/javascript], Strict-Transport-Security[max-age=63072000; includeSubDomains; preload], Title[Root.cz - informace nejen ze světa Linuxu], UncommonHeaders[x-networkmanager-status,content-security-policy,x-backend-server,referrer-policy,access-control-allow-header], X-Backend[web2 D=126273 t=1677330589429008, web3-new], nginx[1.14.2]

With proxy

$ whatweb --proxy localhost:8118 https://www.root.cz/ 
ERROR Opening: https://www.root.cz/ - SSL session is not started yet

Curl / wget ang others go well through the proxy (privoxy in my case)

$ curl -I --proxy localhost:8118 https://www.root.cz/ 2>&1|head -n 30

Workaround - It works using proxychains:

$ proxychains whatweb https://www.root.cz/ 
[proxychains] config file found: /home/mambroz/.proxychains/proxychains.conf
