Thanks Elbert !
While I am here, I have discussed wappalyzer on a prominent french forum and someone told me SPIP had the information directly into the header like this :
Composed-By: SPIP 2.0.2 @ www.spip.net + cfg(1.10.5),crayons(1.1),notifications(0.4),selecteurgenerique(0.2),svn_update(0
.32),topten(0.1),autorite(0.9.2)
As you can see you can even find addon information (not sure that’s good for security to have rev numbers too, though).
Are there many CMSes using this method ?
@dev team : Could we add it to modx, if there is no argument against it, that is ?
