connection pooling

Hi,

We want to allow customers the ability to view their account online, the customers are currently internet users created via transaction SU05.

These customers may but goods from us, but not at a p rofit, we are a local authority in the uk.

Is it possible to create a SAP connection string that log's an SU05 ( internet user ) into SAP for the purpose of calling a BAPI...?

or is it possible to create a connection pool and re-use that pool... for example we may simply want to show a dynamic list of prices for items obtained in real time from SAP - before a user would log in...?

Regards
