Logger throwing an error

[juanp123]

Turning on logging with

RewriteLog "log.txt"
RewriteLogLevel 9

cause an error
Failed to map the path '/log.txt'.

pathRoot = Path.DirectorySeparatorChar.ToString();

Line 217: // our web application root directory
Line 218: if (pathRoot == Path.DirectorySeparatorChar.ToString())
Line 219: path = HostingEnvironment.MapPath( path);

Source File: C:\Orchard.Source.1.6\src\managedfusion-rewriter-master\src\RuleSet.cs Line: 219

I believe what you want in the code above the error is as follows, so that the mapping is relative to the application path. I have not tested all the code paths though, so this may introduce other errors.

path = "~" + pathRoot + path;

(and not path = pathRoot + path; )
