0 | 0 | Does selenium automatic follow redirects? Because it seems that the webdriver isn't loading the page I requested.
And when it does automatic follow the redirects is there any possibility to prevent this?
ceddy | false | 21,173,816 | 0.197375 | 0 | 0 | 1 | No, Selenium drives the browser like a regular user would, which means redirects are followed when requested by the web application via either a 30X HTTP status or when triggered by javascript.
I suggest you consider a legitimate bug in the application if you consider it problematic when it happens to users. | 0 | 3,114 | 0 | 2 | 2014-01-16T22:01:00.000 | python,selenium,selenium-webdriver | Selenium prevent redirect | 1 | 1 | 1 | 21,173,887 | 0 |
