Resources Blacklisting/Whitelisting

Thanks to this powerful feature, you will be able to measure the performance of any web page while blocking one - to many - of its resources.

Blacklist feature can be used on various and numerous purposes. Here are a few examples:

  • Ignore a resource that may tamper the overall loading time of your web page,
  • Compare one single page's performances with or without social widgets (facebook, etc.) or any other specific resource,
  • Measure your web page performances while excluding all of the external resources to focus on those hosted on your own domain.

2 fields (Blacklist & Whitelist) are available in our advanced settings area. Each of them can be filled with several values (one per line).

  • In the blacklist field: type in the resources name you'd like to block specifically. All the requests containing the typed character strings will then be blocked. For example: enter "connect.facebook.net" to block the Facebook widgets.
  • In the whitelist field: there you can define the only requests to authorize, excluding all the other ones. Example : if you want to test your example.com website excluding all of the external resources, then just enter "example.com" in this field.

TIP!
For advanced needs, you can use regular expressions within these 2 fields. Here are a few useful tips:

  • ".": any character (not optional)
  • ".*": any character, 0, 1 or many times
  • [a-z]: indicates a class, here the letters a through z
