Multiple odbc queries

Hi All, I have the problem. We have an application and we are using PHP. The startup page provides the user with a number of links. A link calls a php page where a call to the database is issued. The problem is with difficult queries, then it takes some time to process and the user is a little imaptient and before the request is processed anoter request is done, and if the user is very impatient the multiple times. So for one user on the server a number of database connections and transactions are running which is slowwing down the complete server. WHat is a neat way to solve this ? Kind regards, Marco Laponder mlr@interchain.nl
