Hello,

I noticed Keeweb is using this service to download favicons. However it does not download all favicons.

For example: GET https://favicon-antelle.rhcloud.com/www.dailymotion.com
Expected result: the server sends the favicon of dailymotion.com
Actual result: server sends a 404 status

https://www.google.com/s2/favicons?domain=www.dailymotion.com works well.

Two possible fixes could be:

• get PNG icon if ICO is not found
• if PNG icon is not found, follow http redirections (like Location header and meta http-equiv="REFRESH") until no other redirection, then follow link rel="icon" if provided

The recent addition of throttling makes a self-hosted instance block trusted sources, so I needed to manually edit the file to override the settings:

• IP_THROTTLING_MS = 0;
• IP_THROTTLING_AGGRESSIVE_LOCKDOWN_DETECTION_THRESHOLD = 0;

Please make these configurable from env. The defaults can be your current values if the env values are empty.

Favicon can't be detected in the following case:

<link href='/template/new/images/favicon.ico' rel='icon' type='image/x-icon' />

Request: https://favicon.keeweb.info/gmail.com returns "No favicon", should return favicon for mail.google.com: https://favicon.keeweb.info/mail.google.com

Hi, this project is awesome, however, there are some domains that doesn't seem to return anything as favicon even though they have one.

Example: https://services.keeweb.info/favicon/resources.infosecinstitute.com

How is this possible? :)
