Help with pool member select based on SOAP query

Hi,

 

 

I'm trying to write an iRule and/or external monitor. Need to send the client requests to the server with lowest number returned from a SOAP request. The problem is that that monitors return either up or down. I need a number to evaluate.

 

 

Basic flow:

 

 

1) client sends HTTP post/get to BigIP

 

2) BigIP queries all pool members with a SOAP post and expects a number returned

 

3) BigIP send the client request to the pool member with the lowest number returned in step 2.

 

 

Ideas?
