SEO Urls in ASP.NET Core sind extrem simpel, alles was man braucht ist eine Route an der Action. Bei Interesse kann man die URL auch auswerten, muss man aber nicht.
``` C#
[Route("/Blog/ViewPosting/{id}")]
[Route("/Blog/ViewPosting/{id}/{title}")]
public IActionResult ViewPosting(int id)
{
[...]
return View(posting);
}
```

Heute hab ich ein wenig Caching in den Blog eingebaut, als Inspiration hatte ich die Links oben.
Zuerst wird die Program.cs angepasst
``` csharp
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddResponseCaching();
var app = builder.Build();
app.UseStaticFiles(new StaticFileOptions
{
OnPrepareResponse = ctx =>
{
string path = ctx.File.Name.ToLower();
if (path.EndsWith(".css")
|| path.EndsWith(".js")
|| path.EndsWith(".gif")
|| path.EndsWith(".jpg")
|| path.EndsWith(".png")
|| path.EndsWith(".ico")
|| path.EndsWith(".woff2")
|| path.Contains("/blog/getimage/"))
{
var maxAge = new TimeSpan(7, 0, 0, 0);
ctx.Context.Response.Headers.Append("Cache-Control", "max-age=" + maxAge.TotalSeconds.ToString("0"));
}
else
{
//Request for views fall here.
ctx.Context.Response.Headers.Append("Cache-Control", "no-cache");
ctx.Context.Response.Headers.Append("Cache-Control", "private, no-store");
}
}
});
```
Und nun pass wir wir noch die GetImage Funktion an
``` csha
```
