asp.net - IIS URL Rewrite issue with Tilde (~) -

i have legacy urls need redirect have tilde (~) part of url. i'm having issues getting iis rewrite rules work.

old url: http://www.example.com/~/media/something/whatever.pdf

need redirect to: /whatever

i have following rules in place:

web.config

<rewrite>     <rewritemaps configsource="rewritemaps.config" />      <rules configsource="rewriterules.config" /> </rewrite> 

rewritemaps.config

<rewritemaps>     <rewritemap name="legacy urls">         <!--does not work-->         <add key="~/media/something/whatever.pdf" value="/whatever" />           <!--works-->         <add key="/testing123" value="/whatever" />      </rewritemap> </rewritemaps> 

rewriterules.config

<rules>     <rule name="redirect rule1 legacy urls" stopprocessing="true">         <match url=".*" />         <conditions>             <add input="{legacy urls:{request_uri}}" pattern="(.+)" />         </conditions>         <action type="redirect" url="{c:1}" appendquerystring="false" />     </rule> </rules> 

i'm thinking must need escape tilde, perhaps html encode: ~

( http://www.ascii.cl/htmlcodes.htm ) or url encode.

otherwise must interpreting ~ differently, la application home.
