WebRootPath in DXP

Tomas

Hello,
I'm having trouble getting the WebRootPath to work in DXP, Optimizely 12.
In startup.cs im using this code and it returns an empty string

var epiWebHostingEnvironment = app.ApplicationServices.GetRequiredService<IWebHostingEnvironment>();

epiWebHostingEnvironment.WebRootPath

Same thing in a scheduled job

private readonly EPiServer.Web.IWebHostingEnvironment _env;
if(string.IsNullOrEmpty(_env.WebRootPath))
{
return "Job terminated. WebRootPath is empty!";
}

Is this an upgraded project from CMS11? In many cases those lack a wwwroot folder which is what WebRootPath will look for. In that case, either specify the path in your startup or use ContentRootPath instead.

Try IWebHostEnvironment.WebRootPath (from the Microsoft.AspNetCore.Hosting namespace).

I’ve already tried that, but it didn’t work in DXP.

That's interesting. I have a site in DXP that use it many places. Do you have custom initialization code in Program.cs?

And also, you can inject IWebHostEnvironment in the Startup constructor, capture it in a private field for use in the ConfigureServices method. Probably also in the Configure method.

FYI, this is the answer I got from the support.

As the environment at DXP is Linux OS inside a docker container, therefore, it's not possible to get a correct ContentRootPath or write files to web disk.
So you may need to find an alternative solution, such as storing XML sitemap in the database and create a custom MVC routing to return the sitemap content programmatically.

It sounds right.
You can probably get it to work anyway. But since it is a sitemap file, which should be persistent until next update, it may be more wise to store the files as blob files (maybe in a custom content root folder) or something else.

Why store the sitemap at all? Typically we generate them using a webapi, just add some memory cache to prevent request flooding.

Stefan Holm Olsen - Aug 04, 2025 15:35

Depends on the kind of site. Some huge commerce sites might not want to generate it on demand. Especially not if it gets a lot of traffic.

Instead of creating your own implementation for creating XML sitemaps, why not try the following package, I have used this in many projects and it works great Geta/geta-optimizely-sitemaps: Search engine sitemaps.xml for Optimizely CMS 12 and Commerce 14
