Ok, in the first page, which use a tag, I generate 10 random numbers. and generate a SQL statement containing this numbers like the following: SELECT * FROM table WHERE id in ( 2, 3, 5, 10, .... etc). I use a string to hold the " in " statement and bound it to the whole query string.
After submitting the page, I need to check the validety of the answers, for the same questions. So, I store the inStr in a session and read it in the second page. Regarding concurrency issue, I think that I don't need to synchronize random number generation. Because I don't have a problem for multiple requests to have the same set of questions.
