Any suggestions for effectively testing AJAX enabled web pages using MSVS Tester Edition Tools? |

'|' does not do short-circuit evaluation in boolean expressions. '||' will stop evaluating if the first operand is true, but '|' won't.
In addition, '|' can be used to perform the bitwise-OR operation on byte/short/int/long values. '||' cannot. |
