I'm a front-end web developer at a company using Java on their server. As a front-end developer, I'm concerned with the HTML structure that the server produces, but I don't have control over anything our back-end team produces. Rather than ask someone on that team, I would like to gather knowledge from the Stackoverflow community so I can communicate intelligently with the back-end team. So, I am curious as to what would cause certain JSP tags to appear in the rendered HTML that is sent to the browser. We have tags in our HTML source such as:

<flow:fileRef id="vfileColor" fileId="vfile.color"/>
<flow:fileRef id="StyleDir" fileId="StyleDir"/>
<flow:fileRef id="vfileStylesheet" fileId="vfile.stylesheet"/>

I am more interested in knowing why these appear, not as much about what they do. Is there a server setting for Tomcat/Apache/etc. that would hide these tags from the browser? Any information would be helpful. Thanks in advance.
