Yes, since Moin can understand request parameters in order to interpret the 
query parameters in URLs or the values of form fields, it will be able to 
accept such requests. Typically, you would use an action to handle them, and 
there are a few in MoinMoin/action that might be informative.

I recommend starting off with a simple action, taking something like the 
bookmark action as an example. You will provide an execute function...

def execute(pagename, request):
    ...

...and the request parameters will be provided via request.values as a 
mapping. The more difficult part will involve writing the information 
somewhere meaningful.

If you just want to write to an arbitrary file, you can use normal Python 
functions to do that, although it might be interesting to write to a location 
within the wiki/data hierarchy. The MoinMoin.action.AttachFile module provides 
an interface to attachments, which could be one solution.

You can also edit pages within actions and thus log things to pages. This will 
involve the MoinMoin.PageEditor.PageEditor class whose API is demonstrated by 
various actions.

Finally, Moin tends to block "robots" making requests. This may not be a 
problem for you since you probably won't set a user agent string that matches 
one of the known robots, but it is worth remembering in case Moin rejects 
requests.
