Primefaces graphicImage without ?pfdrid_c=true

I am trying to render a graphic image in primefaces but always returns a 404. In Chrome Debug I can see the address image like this:

/UltracarWeb/Images/1427303591376_image.png?pfdrid_c=true"

Using the Chrome Debug I changed for:

/UltracarWeb/Images/1427303591376_image.png?pfdrid_c=false" , then the image is rendered.

I call the graphicImage in xhtml this way:

 <p:graphicImage  style="max-width: 110px; max-height: 140px;"
                 value="#{product.PhotoUrl}"                                                          
                 rendered="#{not empty product.Url}">                                                        
</p:graphicImage>

I already tryed with cache false and true, and still not work.

The url is not empty because I checked this in the Debug. Debugging the java code I saw the product.url without the ?pfdrid_c=true, but in browser Debug the ?pfdrid_c=true appears.

This ?pfdrid_c=true is a primefaces constant do refers the dynamic cache, but I don't know how can I remove it?

I have had the same problem with this component of primefaces to images, because it adds the parameter ?pfdrid_c=true used to control the Cache-Control

I was using it like this (primefaces element):

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:p="http://primefaces.org/ui"...>


<p:graphicImage value="#{product.PhotoUrl} />

and I chose to use this other jsf element that works perfectly for me since it does not introduce parameter:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"...>


<h:graphicImage value="#{product.PhotoUrl} />

This works only if the value is a String representing an URL but this does not work if the value is a DefaultStreamedContent. This isn't supported by <h:graphicImage>
