פג התוקף של הסשן של המשתמש

שלום

פג התוקף של הסשן של המשתמש

What does this mean? Is the first word vocalized פָּג or פַּג? In the former case, it would, of course, mean 'to stay cold/insensitive'. Also, is סשן a loanword from English? If so, how do Israelis vocalize it?

אני מודה לכם מאוד

פג means 'expired' here.
סשן = 'session'. It is not a Hebrew word, just transliterated from English.
