Hi,
it seems that sysops often submit edits to the Main Page that don't
actually change anything, and in their edit summary they give vague
indications of caching problems.
Now apparently they came up with the idea of placing an HTML comment in
the Main Page, <!-- cache purging value: red-->, and keep changing that
word ("red" in this case) to something else.
This strikes me as a major pollution of the article history as well as
wasted effort.
What is this all about? What is the caching problem? Can it not be
solved by technical means?
Thanks,
Timwi
