+Summary: ASP.NET failure on OS X because of incorrect case sensitivity check
+
+Download, compile, and install Mono and XSP on Mac OS X.  Go to the XSP tests directory and 
+start XSP in the interpreter.  Hit any page, and you will see the error:
+
+   "Both Web.config and web.config exist"
+
+The issue is the way that Mac OS X's HFS+ filesystem handles case sensitivity.  
+In HFS+, case is stored, but is not exactly observed.  So, if I create a file on my filesystem called 
+"Web.config", when I `ls`, it will show up as "Web.config".  But, if I vi the lowercase version 
+("web.config"), it will open the original file.  Hence, case is stored, but the filesystem is not truly 
+case sensitive.
+
+The problem in Mono occurs in the GetConfigFromFileName(...) on line 136 of 
+WebConfigurationSettings.cs.  This method checks to see if "web.config" exists, and then checks 
+to see if "Web.config" exists.  If both exist, it throws an exception, which kills any ASPX in its 
+tracks.  On my Mac OS X machine, only one web.config file exists, but it can be reached with 
+either name because of the aforementioned case sensitivity issue.
+
+The check that is performed in the code looks at DirectorySeparatorChar to determine if you are 
+on a UNIX machine, and then assumes case sensitivity.  The conditional currently reads 
+something like:
+
+   if (DirectorySeparatorChar == '/' && isUpper && isLower) {
+      throw Exception;
+   }
+
+A fix would be for the conditional to read:
+
+   if ((platform != MACOSX) && DirectorySeparatorChar == '/' && isUpper && isLower)
+      throw Exception;
+   }
