Define connection pool size in iis 7 (not by connection string)

So our connection string is constructed from app settings rather than stored as an actual connection string. Stupid I know, was done years before I was here.

Question is, can I do something in the web.config or in IIS itself to define the processes default connection pool from a configuration standpoint so I don't have to change the code that creates t开发者_Go百科he connection string and deploy a new version of the dal to increase the connection pool.

Ideas?

This cannot be done. Connection pool size can be defined only by connection string.
