irule assistance on internal maintenance web page

I am an irule novice. 

 

I have 2 irules that are identical except for the very first line. 

 

One has :

 

if { ([HTTP::path] contains "/darwin") } {

 

and the other has 

 

if { [active_members [LB::server pool]] < 1 } {

 

One is a conditional that checks the path for a certain character string and the other one checks to see if the pool is empty. 

 

The one that checks for pool empty works just like it should. 

 

It has some ifiles that have company logos and colors and formatting.

 

The one that checks the path for text sort of works and uses exactly the same ifiles but does not show the logos and formatting. 

 

Any thoughts?

 

I am attaching the IRULES and a couple of screen shots of the different outcomes.

    not an answer but more information -

    when it does not work (checking for path contains "/darwin") from some log statements I see this in the log
