HELP! CustomerSession is empty when rewriting urls from .aspx to .html

Hello,

I am facing a blocking problem due to the rewriting of urls from .aspx to .html (absolute need from my customer)

The symptom is surprising, because sessions and cart are routinely lost for anonymous users, but not for registered users.
For example, an anonymous user select a product, then go to his cart: the basket is still empty.
I the user is already logged when filling his cart: no problem!
If I stop rewriting urls from .aspx to .html, the problem disapear!!!

When this problem appears, in debug mode, I saw that when cart is loading in GetCurrentShoppingCart method, NopContext.Current.Session still returns null...

Below you can see a part of my web.config file, did I forget to configure something else?
Thanks for your help

This is my

<httpHandlers>
  ...
  <add verb="*" path="*.html" type="System.Web.UI.PageHandlerFactory" />
</httpHandlers>

<system.webServer>
  ...
  <handlers>
    ...
    <add name="HtmlHandler-Integrated" path="*.html" 
        verb="GET,HEAD,POST,DEBUG" type="System.Web.UI.PageHandlerFactory" 
        modules="ManagedPipelineHandler" requireAccess="Script" preCondition="integratedMode" />
   </handlers>
</system.webServer>

Open CommonHelper.IsContentPageRequested() method and replace

if (!request.Url.LocalPath.ToLower().EndsWith(".aspx") &&
!request.Url.LocalPath.ToLower().EndsWith(".asmx") &&
!request.Url.LocalPath.ToLower().EndsWith(".ashx"))
{
      return false;
}

with

if (!request.Url.LocalPath.ToLower().EndsWith(".aspx") &&
!request.Url.LocalPath.ToLower().EndsWith(".asmx") &&
!request.Url.LocalPath.ToLower().EndsWith(".ashx") &&
!request.Url.LocalPath.ToLower().EndsWith(".html"))
{
      return false;
}

you are awesome!

It works perfectly now, thanks so much!!!

Just another question on the same topic : Before html, I tried to rewrite to htm, but I had a problem with real htm pages like ErrorPage.htm.
Do you think there is a solution to use the same extension (htm) for static pages and dynamic rewriten pages?

Thanks

You can use both of them (htm and html)
