How to enable preserve log option for chrome developer settings->Preferences->Preserve log upon navigation, using chromeoptions.add_argument or by adding the pref to DesiredCapabilities or any other way programmatically.

You can get redirects from performance logs. According to docs and github answer here is what I've done in C#, should be possible to port in Python:

var options = new ChromeOptions(); var cap = DesiredCapabilities.Chrome(); var perfLogPrefs = new ChromePerformanceLoggingPreferences(); perfLogPrefs.AddTracingCategories(new string[] { "devtools.network" }); options.PerformanceLoggingPreferences = perfLogPrefs; options.AddAdditionalCapability(CapabilityType.EnableProfiling, true, true); ptions.SetLoggingPreference("performance", LogLevel.All); var driver = new ChromeDriver(options); var url = "https://some-website-that-will-redirect.com/"; driver.Navigate().GoToUrl(url); var logs = driver.Manage().Logs.GetLog("performance"); //all your logs with redirects will be here 

Looping through logs, if message.params.redirectResponse.url is equal to original URL then message.params.request.url will contain redirect URL

Node.JS using webdriverio:

var options = {     desiredCapabilities: {         browserName: 'chrome',         loggingPrefs: {             'browser': 'ALL',             'driver': 'ALL',             'performance': 'ALL'         },         chromeOptions: {             perfLoggingPrefs: {                 traceCategories: 'performance'             },         }     } var client = webdriverio.remote(options); await client.url(url); var logs = await client.log('performance'); var navigations = parseLogs(logs, url);  function parseLogs(logs, url) {     var redirectList = [];     while (true) {         var targetLog = (logs.value.find(l => {             if (l.message.indexOf(url) == -1)                 return false;             var rootMessage = JSON.parse(l.message);             if (((((rootMessage || {}).message || {}).params || {}).redirectResponse || {}).url == url)                 return true;             return false;         }) || {}).message;         if (!targetLog)             break;         if (redirectList.indexOf(url) != -1)             break;         redirectList.push(url);         var targetLogObj = JSON.parse(targetLog);         var nextUrl = ((((targetLogObj || {}).message || {}).params || {}).request || {}).url;          if (nextUrl) {             url = nextUrl;             continue;         }         break;     }     return redirectList; }
