during configuration SAS, I check port 80 (for SAS web server HTTP port) and I found it busy so, I change it into 87. after complete SAS configuration I was surprised that port 87 restricted ports in browsers( google chrome and firefox ) and it need to manually setting to make those browsers allows to HTTP with port 87 work. So, I needed to make browsers setting on all PC's that used SAS (it is headache). So how I can change the HTTP port from 87 to 83.
