Use a text file for web filter

Yes. Please open "Account Manager"-> Web Filter-> Click the button "..." on the right of the blank field which is for inputting filter sites-> select the text file you prepared for web filter.

Below is a sample format for that text file. Please note you need to make sure it is one item per line divided by semi-colon.

*.inhealthrecords.com;

inhealthrecords.com;

*.sleepcmi.com;

sleepcmi.com;

fedex.com;

*.fedex.com;

*.fedex.com:433;

fedex.com:433; 
*.pahcom.com;

Notes: 

1. There are no limits to the number of lines the text file can have.

2. Keep in min that you should write sitename.domain for cases when user will enter the web address without "www". So to block  any site completely, you should write this on filter: 

*.yahoo.com:443;

yahoo.com:443;

yahoo.com;

yahoo.*:443;

*.yahoo.*;
