I have a baffling situation occurring on a web server running IIS
(Windows Server 2003). There is one particular page which sometimes
generates errors trying to execute a particular 'require' statement.
The file which is being included contains a simple banner and is
included at the head of every page on our site. Yet the 'require'
statement sometimes fails with this message:
Error in D:\inetpub\wwwroot\conferences\default.php
On line 12, error #2, in D:\inetpub\wwwroot\conferences\default.php:
"require(../apr03ban.html) [<a
href='function.require'>function.require</a>]: failed to open stream: No
such file or directory"
The error always occurs in this file, default.php, and not in any other.
Further, analysis of the errors reveals the following pattern. In every
case, one of the following is true:
A) The user agent contains one of the following patterns:
Googlebot/2.1; +http://www.google.com/bot.html
Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp
msnbot/1.0 (+http://search.msn.com/msnbot.htm)
CazoodleBot Crawler; http://www.cazoodle.com/cazoodlebot
psbot/0.1 (+http://www.picsearch.com/bot.html)
or,
B) The referrer looks like one of these:
http://search.msn.com/results.aspx?q=seton+homeschool&FORM=MSNH
http://search.msn.com/results.asp?FORM=sCPN&RS=CHECKED&un=doc&v=1&q=homeschool%20conference
http://search.live.com/results.aspx?q=catholic+homeschooling&first=11&FORM=PERE
As you can see, there is a definite pattern here. The error is not
occuring purely at random. However, this brings me no closer to a solution.
Does anyone have any ideas for possible explanations, or for what kinds
of tests I could do to track down the cause of the problem? Thanks.
