How can we allow dots in ASP.NET MVC urls? - asp.net

Question

I have a website developed in MVC 5 that perform search in inventory and the url is like this
http://localhost:56099/search/SQUARE
This url works, it redirects to Search controller and Index action with search query as SQUARE and gives the correct result. But, if I enter 2 dots as a search query it just takes me to my root page. The url will be like this
http://localhost:56099/search/..
it's strange because same thing works when passing single dot or multiple dots, so I can't find any technical reason why it is getting neglected.
I have done following things in Web.Config:
<modules runAllManagedModulesForAllRequests="true"> for accepting others characters also in search query.
relaxedUrlToFileSystemMapping="true"
But no success and I can't find any real reason for this weird behaviour. Any advice.

Answer 1

you should register the search route in your "RouteConfig.cs" file
routes.MapRoute(
"SearchRoute",
"Search/{*pathinfo}",
new { controller = "Search", action = "ActionName"});

Answer 2

You have the problem with .., because .. in your case is detected as relative URL, which indicates moving up to the parent directory(or root in your case), essentially stripping off everything up to the previous slash in the the Base URI.
UrlRoutingHandler in web.config should help you.
<system.webServer>
<handlers>
<add name="UrlRoutingHandler"
type="System.Web.Routing.UrlRoutingHandler,
System.Web, Version=4.0.0.0,
Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"
path="/Search/*"
verb="GET"/>
</handlers>
</system.webServer>
Then every URL starting with /Search will be considered as MVC URL.
Also you could try:
<system.webServer>
<security>
<requestFiltering allowDoubleEscaping="true" />
</security>
</system.webServer>
