title: Maximum number of <iFrame> tags per web page
body: <p>For a website it is possible to include multiple iFrames for integration of external content. I know that there are other better ways to include such content, but I wonder if there is a browser-specific limit for the number of allowed iFrames on one web page?</p>
  
  <p>Now I thought that there are two possible browser limitation: </p>
  
  <ol>
  <li>the number of connection that are needed for including the iFrame resources and</li>
  <li>the concrete maximum number of allowed  tags.</li>
  </ol>
  
  <p>For (1): I figured that e.g. Mozilla Firefox (v17) has config parameter for maximum number of connections to a server (<code>network.http.max-persistent-connections-per-server</code>) and an overall limited number of concurrent connections (<code>network.http.max-connections</code>). See <code>about:config</code>.</p>
  
  <p>For (2) I cannot find any information. Except that there is a higher resource demand and other performance issues there is no fixed limitation for those tags on one page.</p>
  
  <p>Do you have any other information?</p>
  
  <p>Thanks</p>
