Error - A potentially dangerous Request.Path value was detected from the client

During calling REST service from client end i came across the below error..

"A potentially dangerous Request.Path value was detected from the client"

For this, i found following solution in web.config file of REST end and it works for me


- For httpruntime put requestpathinvalidcharacters="" & requestvalidationmode="2.0"
- For pages put validaterequest="false" 
- Both of these tags are located under configuration --> system.web

Also, there are some useful links too for this error
(1) Getting “A potentially dangerous Request.Path value was detected from the client (&)”
