Request.Form("test1") will return an empty string if the field does not exist, but also when users leave it blank. A better solution is to use Request.FormCount("test1"), which will return 0 if the field does not exist.

is there a way to know whether the input text name is defined or not?
ex. i have <input type="text" name="test1">
how can i know that "test2" doesn't exist?
