Sergiu,
Not a mystery, I think Google is causing some of the errors (exceptions
for old pages). Sometime these links used to be there, Google indexed
them, and now it tries to reindex them.
The rest of the exceptions are indeed spam attempts. I've seen them too
on one of the servers I manage, but they don't succeed in doing
anything. Probably a spambot trying URLs that work on other sites, but
that don't affect XWiki.

I searched the site, and couldn't find that
string anywhere.
I know, I have searched the site for urs appearing in different
exceptions ...
I don't think that is an URL generated by
XWiki, so I'd say that most
probably somebody browsing the site accidentally entered a wrong URL.
Does that exception appear more than once?
In fact, yes, I get such exceptions all the time (see the latest three
below). Interesting, while in exceptions with url (eg 1st and 2nd), urls
change, the third exception
([http://iiscs.wssu.edu/xwiki/bin/viewrev/Photos/IISMembers?xpage=pr
int&rev=1.158]) reoccurs. Perhaps these are two different cases. I did
have an older version of xwiki installed before, where I think I had a
page IISMembers, however, I deleted that installation completely,
including the xwiki database (in MySQL) and did a new installation, so
there is nowhere this page could come from ... Complete mystery ...
As to the first case, I wonder can this browsing be
done by programs
that try to insert somehow various urls in the wiki site, and if it is
so, whether can I prevent this ... also, if this is the reason, should
it really cause exception but not just a warning message that there is
no such document?
Normally, it should say that the document does not exist, but the URL is
so malformed, that the engine gets an error. I'll try to fix this, but
it will help you only if you upgrade to the next XWiki version.
As long as these exceptions don't affect the users, but just confuse
Google and fill the logs, I'd say they are not of great importance.
Watch http://jira.xwiki.org/jira/browse/XWIKI-2091 for details.
Thanks a lot for your help,
Darina
