response collect error payload respond

I have a stupid application that is throwing errors but using an http status of 200 to do so. I have written this irule snippet to replace the responses,

 

 

 

when HTTP_RESPONSE {

 

if { [HTTP::status] == 200} {

 

HTTP::collect 50 }

 

}

 

when HTTP_RESPONSE_DATA {

 

if { [HTTP::payload] contains "reported an error" } {

 

HTTP::respond 404 }

 

}

 

 

 

 

 

 

 

 

 

 

 

and it works, but i'm curious about the HTTP::collect element. I have set it to 1 and set it to a million, and my connection doesn't stall and it works and the response time is about the same. what is a recommended collection amount? what is the unit of measure for integers and this command? i'm assuming bytes.

 

 

 

 

 

 

 

Thanks,
