How to manage sessions(IEnterpriseSession) across multiple users?

Question

Assuming that we are going to have only one user for our web-app to access the BO-ReportServer.
Are we supposed to fetch the IEnterpriseSession, using the following code for every user who is trying to access the WEBI report using BO-SDK from a web application.
CrystalEnterprise.getSessionMgr().logon
Example:
When User_One, logs on to the webapp start a new HttpSession and then do a CrystalEnterprise.getSessionMgr().logon
When User_Two, logs on to the webapp start a new HttpSession and then do a CrystalEnterprise.getSessionMgr().logon
Questions:
1. Is this right approach
2. If yes, So does this keep going, considering if our webapp has around 500 concurrent users then will this be scalable
3. If no, then I wondering if the IEnterpriseSession will be threadsafe
Confusion:
Just confused if IEnterprise session is similiar to a datasource(for db connections which manages the connection pool) or is it more like HTTPSession, which is created for every individual user accessing the application.

Answer 1

Yes total users should be around 5000, but there could be around 500 users accessing concurrently. Besides we are using to BOE to show a dashboard, with charts and graphs(using the HTMLView) so we will have to 500 concurrent IEnterprise sessions. I just hope that:
1. Each session is unique(independent thread) although they have logged on using the same credentials
2. The CMS server can scale upto this number(500). Don't know if there are some caching options available?
