Description of my issue:

Hi Nicholas,

The WAF, on at least a few of my sites, is sometimes blocking people who are viewing events created in JEvents. The reason is always "template= in URL" but I'm confused about this for two reasons:

  • The URLs look like this: upcoming-events/icals.icalevent/-?template=component&evid=31&icf=1 . In WAF Configuration, I see that "component" is one of the allowed words by default in the "List of allowed tmpl= keywords" section, so I can't figure out why these URLs are being blocked.
  • The URLs being blocked actually do seem suspicious to me, so perhaps the system is correct in blocking them. For example, this one was blocked - http://jrculinaryteamcanada.ca/upcoming-events/icals.icalevent/-?template=component&evid=48&icf=1 - and going to it causes a "ics" file to be downloaded. On the site's events themselves, like this one - http://jrculinaryteamcanada.ca/upcoming-events/icalrepeat.detail/2012/05/28/48/-/ika-100-rules-hot-run-prep-7-00am-10ppl-pdr-jj-s - there is no option top create an .ics file. Others, like you see in the attached screen capture, bring up an error that says "The template for this display is not available. Please contact a Site administrator" and again, I can't seem to reach these URLs by simply browsing the site.


So, I'm basically wondering (a) why AdminTools is using the reason "template= in URL" to block URLs with template=component in them, and (b) if you think it's actually working as it should since these URLs seem suspicious.

Thanks!
Chris

Hi Chris,

Ah, you almost had me with that one :) Please note that tmpl= and template= are different parameters. The template= in the URL is someone trying to do visual fingerprinting on your site and Admin Tools is very correct in blocking the request.
