4.3.3.3 Missing magic string

When running a GetFeatureInfo request with the info_format set as text/html, you will get an error like the below, if you do not include a magic string in each of your HTML template documents.

Content-type: text/xml isValidTemplate(): Web application error. Missing magic string, template-file doesn’t look like a MapServer template.

You need to add <!-- MapServer Template --> to the top of ALL templates.

Example the exemplar template query footer.html is:

<!-- MapServer Template -->
</body>
</html>

The recently updated exemplar service kits include this NEW requirement, but those updating from older services might miss this.
