/**
* document-builder.sjs can be used to dynamically build documents that will be used in
* mochitests. It does handle the following GET parameters:
* - file: The path to an (X)HTML file whose content will be used as a response.
* Example: document-builder.sjs?file=/tests/dom/security/test/csp/file_web_manifest_mixed_content.html
* - html: A string representation of the HTML document you want to get.
* Example: document-builder.sjs?html=<h1>Hello</h1>
* - headers: A <key:value> string representation of headers that will be set on the response
* This is only applied when the html GET parameter is passed as well
* Example: document-builder.sjs?headers=Cross-Origin-Opener-Policy:same-origin&html=<h1>Hello</h1>
* document-builder.sjs?headers=X-Header1:a&headers=X-Header2:b&html=<h1>Multiple headers</h1>
* - delay: Delay the response by X millisecond.
