Conversion error for b64encode

Hey all,

 

 

I'm experiencing the same b64decode error " - conversion error invoked from within "b64decode [lindex $::banner_prg_png_class 0]"

 

 

I've encoded a png image as directed by this post http://devcentral.f5.com/wiki/default.aspx/iRules/LTMMaintenancePage.html

 

 

I've created the file and removed all of the 'returns', created the class, and associated the iRule with the VIP.

 

 

This code fails:

 

 

when HTTP_REQUEST { 
 log local0.info "Rule initiated" 
 HTTP::respond 200 content [b64decode [lindex $::banner_png_class 0]] "Content-Type" "image/png" 
 log local0.info "Response Successful"    
 }

 

 

When I replace the "[lindex $::banner_png_class 0]" with the actual b64 text - it works just fine.

 

 

What I'm trying to do in the end is to have a 200 respond with a multilined html response with several images, but I can't get past this step...

 

 

Thanks in advance.
