Not able to download a file with % even after url encode

Question

I saved a file , which contains % and %20

when i click on a link,which is pointing to this file. By using javascript am doing encodeURI(filePath).

Getting file not found error, but file is available.

Browser Chrome and IE, Server: IIS Server

actual URl : http://<servername>/<Folder>/PDF/!%2-!@crackerunit&%_20151029203000_0.pdf

encodedURl : http://<servername>/<Folder>/PDF/!%252-!@crackerunit&%25_20151029203000_0.pdf

I do not have any query string values , so am using `encodeURI()` — Badrinarayana, Oct 29 '15 at 15:33
What server are you using? Which browser? Can you post the code you are using? — jazmit, Oct 29 '15 at 15:43

Follow these steps:

 1. Original pdf: !%2-!@crackerunit&%_20151029203000_0.pdf
 Use JavaScript encodeURI: encodeURI("!%2-!@crackerunit&%_20151029203000_0") 
 Resulting output: !%252-!@crackerunit&%25_20151029203000_0.pdf
 Complete url: http://<servername>/<Folder>/PDF/!%252-!@crackerunit&%25_20151029203000_0.pdf
 Once this url is accessed, you receive an exception: A potentially
 dangerous Request. Path  
 value was detected from the client (%). Solve this problem by following  
 step2 

 2. web.config changes:
 <system.web>
   <httpRuntime requestPathInvalidCharacters="" 
   />
 </system.web>

But escape has been depreciated. – Badrinarayana Oct 29 '15 at 16:41
