I’m having trouble showing urls with redirect with an automation tool i’m using so I’m thinking of checking the url for redirects first before opening the popup.
Is it possible to get the redirect URL using javascript (no jquery or other js framework as this is not supported by the tool)?
Thanks!
In theory, yes. In practice, probably not.
In theory you could do an XHR head request to the URL, then check the location header to see if what you asked for is what you ended up getting. XHR will automatically follow 301/302 redirects, so there’s no use checking the status code – Is it possible for XHR HEAD requests to not follow redirects (301 302)
In practice, unless the domain you’re asking is your domain, or has a
Access-Control-Allow-Originheader (I think it’s header), the request will fail due to cross site request restrictions. HEAD XMLHttpRequest on ChromiumIf you’ve got access to the server running your tool, you should be able to whip up a “proxy” page that issues the HEAD request, then you can XHR call your server page and it would return where the HEAD request said you’d end up.
