Hi , 

Does anyone know if variables in the file paths of HTTP requests are calculated 
each time the sampler is executed or only once, upon initialisation? I'm trying 
to use a HTTP sampler in a Loop controller to send a file chunk each time. I 
use the following path: 

${testplan.root}/data/resources/${medium.3gpp.filename}_${current.chunk.index} 

where ${current.chunk.index} increases each time the Loop Controller interates, 
but it seems to keep sending the first file chunk, which leads me to believe 
this is not evaluated each time the sampler is executed. 

Is there a workaround for this?
