CF Dude, What's in the cache?

Make it happen: rapid app development on Kubernetes as a managed service.

Over the weekend I needed to see what was in my cache. I whipped up a quick script to list everything in cache and from there:

  • be able to remove an item
  • view the content of an item (limited to top 10 records)
  • view the metadata of an item.
I've included the code below.
<cfscript>
writeOutput('<h2>CF Dude, What''s in the cache?</h2><div><a href="#cgi.script_name#">Reload</a><br><br></div>');

param name="url.do" default="";

switch (url.do) {
    case "remove":
        cacheRemove(url.item);
        writeOutput("<div style='color: green; font-weight: bold'>Removed #url.item#</div>");
    break;
    case "view":
        writeDump( var=cacheGet(url.item), label="Cache contents of: " & url.item, top=10 );
    break;
    case "meta":
        writeDump( var=cacheGetMetadata(url.item), label="Metadata for: " & url.item );
    break;
}

incache = cacheGetAllIds();
arraySort(incache,"textnocase");
</cfscript>

<cfoutput>
<h3>Cache IDs</h3>

    <table cellspacing="4">
    <cfloop array="#incache#" index="c">
        <tr>
            <td>#c#</td>
            <td><a href="#cgi.script_name#?do=remove&item=#c#">remove</a></td>
            <td><a href="#cgi.script_name#?do=view&item=#c#">view</a></td>
            <td><a href="#cgi.script_name#?do=meta&item=#c#">meta</a></td>
        </tr>

    </cfloop>
    </table>
