I have deployed an asp.net site with a wcf rest service to a virtual directory. It accepts lat/lon in the querystring. IIS is apparently not allowing querystrings that contain a ‘.’. I have found numerious posts on the topic, but cannot seem to resolve the issue.

I have tried enabling parent paths on both the parent website and the virtual directory:

I have already tried the httpRuntime setting for relaxedUrlToFileSystemMapping=”true”

currently I have both parent paths enabled and my httpRuntime settings are:

<httpRuntime requestValidationMode="2.0" requestPathInvalidCharacters="" relaxedUrlToFileSystemMapping="true" />

    I noticed that the Urls you were using have a / rather than a ? which causes the elements to be treated as a path rather than a query string.

    If that was intended and you are using .NET 4.0, you can try using the <schemeSettings> Element (Uri Settings) under configuration:

    <uri>  
    <schemeSettings> 
        <add name="http" genericUriParserOptions="DontUnescapePathDotsAndSlashes" /> 
    </schemeSettings> 
</uri>

    See GenericUriParserOptions Enumeration for the valid values.

    If that was not intended update your template to use the ? mark and you should be ok:

    [WebGet(UriTemplate = "?username={username}&lat={lat}&lng={lng}")]
