Are you sure you want to...

    I noticed the Contents View in site map sometimes does not pick up specific resources under certain conditions. Ex : An item has been identified during a spider scan as a GET request to /content/script, gets added properly to contents view When browsing the site, the same resource gets accessed as a POST request, going through the proxy. This POST request never appears in the contents view, d...

I inspect the Extender tab and I find that the extension I wrote is unloaded. I check the "Loaded" box, the extension compiles, ...
