Re: Server.MapPath & Request.MapPath

The way I look at it, there's a single MapPath method
which is called in different contexts with different parameters.

public virtual string MapPath(string virtualPath)
{
return null;
}

public string MapPath(string virtualPath)
{
return this.MapPath(VirtualPath.CreateAllowNull(virtualPath));
}

internal string MapPath(VirtualPath virtualPath)
{
if (this._wr != null)
{
return this.MapPath(virtualPath, this.FilePathObject, true);
}
return virtualPath.MapPath();
}

public string MapPath(string virtualPath, string baseVirtualDir, bool allowCrossAppMapping)
{
VirtualPath filePathObject;
if (string.IsNullOrEmpty(baseVirtualDir))
{
filePathObject = this.FilePathObject;
}
else
{
filePathObject = VirtualPath.CreateTrailingSlash(baseVirtualDir);
}
return this.MapPath(VirtualPath.CreateAllowNull(virtualPath), filePathObject, allowCrossAppMapping);
}

internal string MapPath(VirtualPath virtualPath, VirtualPath baseVirtualDir, bool allowCrossAppMapping)
{
if (this._wr == null)
{
throw new HttpException(SR.GetString("Cannot_map_path_without_context"));
}
if (virtualPath == null)
{
virtualPath = VirtualPath.Create(".");
}
VirtualPath path = virtualPath;
if (baseVirtualDir != null)
{
virtualPath = baseVirtualDir.Combine(virtualPath);
}
if (!allowCrossAppMapping)
{
virtualPath.FailIfNotWithinAppRoot();
}
string str = virtualPath.MapPathInternal();
if (((virtualPath.VirtualPathString == "/") && (path.VirtualPathString != "/"))
&& (!path.HasTrailingSlash && UrlPath.PathEndsWithExtraSlash(str)))
{
str = str.Substring(0, str.Length - 1);
}
InternalSecurityPermissions.PathDiscovery(str).Demand();
return str;
}

public string MapPath(string path)
{
if (this._context == null)
{
throw new HttpException(SR.GetString("Server_not_available"));
}
return this._context.Request.MapPath(path);
}

public string MapPath()
{
return HostingEnvironment.MapPath(this);
}

Hello rn5a@xxxxxxxxxxxxxx,

There are no difference in this aspect, because the Server.MapPath calls the _context.Request.MapPath(path)
inside its method

Server.MapPath returns the physical file path that corresponds to the
specified virtual path whereas Request.MapPath maps the specified
virtual path to a physical path. Assuming that a file named Hello.aspx
resides in C:\Inetpub\wwwroot\MyFolder, the output of both

Response.Write(Server.MapPath("Hello.aspx"))

&

Response.Write(Request.MapPath("Hello.aspx"))

is C:\Inetpub\wwwroot\MyFolder\Hello.aspx. So what's the difference
between Server.MapPath & Request.MapPath?

Thanks
