 * Hi, I was able to complete the first scan I tried. It worked on ~7,000 of the
   links it found. However, about 100 of the links I get a mix of 403 Forbidden,
   and 404 Not Found errors, but have checked a bunch of these and they are valid.
   One is [https://www.delta.com/](https://www.delta.com/) that is giving a 403 
   as an example. Any ideas what could cause that, or a solution?

 * Hi, thanks for your message.
 * The requests are made from your web server, so in some cases I think it is possible
   to get different responses due the location of your server.
 * For example, here in Spain the link for the delta.com redirects (302) to
    [https://es.delta.com/](https://es.delta.com/)
 * When you receive 403 responses I think it is because the firewall of the destination
   server detects to many requests and ban your server remote IP. Nothing to do 
   here, it depends about how are configured these filters of the destination servers.
 * Kind regards,

 * I can curl to these URL’s directly from the web server by hand without issue.
   I will start a new scan now in the plugin to just make sure it was not something
   else and update shortly. We only have the one link to these ones which were rejected
   so it should not be due to multiple requests.

 * I just did a quick curl variation test. The 403 comes back if I include the user
   agent string from the plugin with my curl request.

 * If I include a referrer with my curl request & the user agent string, then it
   succeeds.

 * Ok, what referrer have you included? To take note about what works for this case.

 * Many thanks jedsta,
 * Maybe the plugin needed a referrer option next to the user-agent to avoid 403
   responses from web servers with agressive scraper filters, I will think about
   it.

 * Thanks, It certainly would be appreciated. I just purchased the plugin after 
   our correspondence. It would make the end results more usable and clean.
