Help with Irules

Hi Paulius,

I'll try to be more clear.

We've 2 pools with 2servers on each. 

Pool A and Poll B by exmeple. When pool A is down all traffic is redirected towards Pool B, and inversely.

We use a API on each server to sent their status to F5. GET /toolkitapi/getfostatus HTTP/1.0\r\n\r\n

Basicaly return of APi is <fostatus>Master</fostatus> or <fostatus>Slave</fostatus>.

That ran fine with this pattern <fostatus>(Master|Slave)</fostatus> configured into the F5.

But, our supplier has updated our servers and with the same API the return is different now.

Return of API: {"fostatus":"Master"} or {"fostatus":"Slave"}.

When our IT team has tried to change the pattern into F5 with {"fostatus":"Master|Slave"} instead of <fostatus>(Master|Slave)</fostatus>.

Impossible to validate the new pattern on F5 each time a error is displayed on F5 GUI.

By exemple, we've tried those combination into F5:

{"fostatus":"Master|Slave"}

{"fostatus":"Slave"}{"fostatus":"Master"}

{"fostatus":"Slave"}|{"fostatus":"Master"}

"{\"fostatus\":\"Slave\"}|"{\"fostatus\":\"Master\"}

But unfortunately, we've always a syntax error from F5. 

One more time, isn't my part of job, don't know F5. I just relate what I see on F5 GUI and my understanding.

Your help is really apreciate.

Kind Regards,

Michaël
