IIS 6 not allowing periods in the querystring

问题

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: http://support.microsoft.com/kb/332117

I have already tried the httpRuntime setting for relaxedUrlToFileSystemMapping="true" http://haacked.com/archive/2010/04/29/allowing-reserved-filenames-in-URLs.aspx

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}")]

Probablly not what you were looking for but I would use UrlEncode:
