Namespace: System.Web
Assembly: System.Web (in system.web.dll)

public void RewritePath (
	string filePath,
	string pathInfo,
	string queryString,
	bool setClientFilePath
public void RewritePath (
	String filePath, 
	String pathInfo, 
	String queryString, 
	boolean setClientFilePath
public function RewritePath (
	filePath : String, 
	pathInfo : String, 
	queryString : String, 
	setClientFilePath : boolean
Not applicable.



The virtual path to the resource that services the request.


Additional path information to use for the URL redirect.


The request query string to use for the URL redirect.


true to set the file path used for client resources to the value of the filePath parameter; otherwise false.

Exception typeCondition


The path parameter is not in the current application's root directory.


The filePath parameter is not in the current application's root directory.

The filePath parameter does not include the content of the pathInfo parameter. For the URL, the filePath parameter is, and the pathInfo parameter is tail.

To ensure that the virtual path that is used to construct paths to resources is not modified, set the setClientFilePath parameter to false. A common scenario in which you might want to set setClientFilePath to false is when you need to rewrite the URL, and you are using themes and redirecting the URL to a resource located in a different folder than the requested resource.
