I have seen a couple of videos and read some documentation and I really want to implement it, so I have created a YARP server-proxy solution, and as a test, I set to the destination, one to google and another one to a local solution, but unfortunately, as the path is replaced to my current local URL (https://localhost:44321/), the destination is not displaying the static files like .js, .css or images. I have tried including app.UseStaticFiles() in my Startup.cs and this does not work. Routes: {
"RouteId": "example",
"ClusterId": "cluster3",
"AuthorizationPolicy": "customPolicy",
"Match": {
"Path": "/example"
},
"Transforms": [
{ "PathRemovePrefix": "/example" },
{
"ResponseHeader": "Source",
"Append": "YARP",
"When": "Success"
}
]
},
{
"RouteId": "verstalocal",
"ClusterId": "cluster4",
"AuthorizationPolicy": "customPolicy",
"Match": {
"Path": "/verstalocal"
},
"Transforms": [
{ "PathRemovePrefix": "/verstalocal" },
{
"ResponseHeader": "Source",
"Append": "YARP",
"When": "Success"
}
]
}
Destinations: Google: Where should I indicate that it has to use the correct resources? Thanks for your help! |

Could you please give me more details, what do you mean to turn on the proxy debug logs? |

Try this, but with everything set to "Debug". |

For both request in my understanding it is proxying to the correct address: external address (google) My local Solution: You will see on the logs I am using AzureAD Authentication, in case the user is not logged in, the https://login.microsoftonline.com/ will be prompted and after that will be redirected. Is it possible that here is the error? public void ConfigureServices(IServiceCollection services)
{
//services.AddMicrosoftIdentityWebApiAuthentication(Configuration);
services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApp(Configuration.GetSection("AzureAd"));
services.AddAuthorization(options =>
{
options.AddPolicy("customPolicy", policy =>
policy.RequireAuthenticatedUser());
});
services.AddControllersWithViews(options =>
{
var policy = new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.Build();
options.Filters.Add(new AuthorizeFilter(policy));
});
services.AddReverseProxy()
.LoadFromConfig(Configuration.GetSection("ReverseProxy"));
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseForwardedHeaders();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapGet("", ctx => ctx.Response.WriteAsync("My Proxy"));
endpoints.MapReverseProxy();
});

Those logs show the success case for the site root, what about the logs for the static resources? Oh, I see your problem. You make the first request to YARP is not designed to re-write response content to fix up links like this. This situation is best handled when the proxy and the destination cooperate using relative paths or tool like x-forwarded-pathbase. |

Correct that is my issue, that they use absolute paths, I am looking into the link you sent me, to try to redirect static files to |

Hi! I have tried to append /verstalocal to Path or Pathbase but this did not work: app.Use((context, next) =>
{
context.Request.PathBase = new PathString("/verstalocal");
return next();
});app.Use((context, next) =>
{
if (context.Request.Path.StartsWithSegments("/static", out var remainder))
{
context.Request.Path = "/verstalocal/static" + remainder;
}
return next();
});My route is: {
"RouteId": "verstalocal",
"ClusterId": "cluster4",
"AuthorizationPolicy": "customPolicy",
"Match": {
"Path": "/verstalocal/{**catch-all}"
},
"Transforms": [{
"PathRemovePrefix": "/verstalocal"
}]
}
"cluster4": {
"Destinations": {
"cluster4/destination1": {
"Address": "http://127.0.0.1:5555"
}
}
}I will really appreciate if you can share any idea or clue. |

If this is just about the {
"RouteId": "static",
"ClusterId": "cluster4",
"AuthorizationPolicy": "customPolicy",
"Match": {
"Path": "/static/{**catch-all}"
}
} |

Thanks again for your answer!!! No, it is not just with the static folder, I do have also some endpoint mapping with Blueprint (it is a python + flask solution), which means, that if I map "static", will work, but my endpoints like As another approach, I have tried to include the prefix in my solution "http://127.0.0.1:5555/verstalocal" so I can catch all of them and then proxying. But when I do that it does me a redirect: I am using "PathPrefix" to set the new prefix... and I also have tried to call it straight in the address, and any of them did not work, in both cases, it is redirecting. {
"RouteId": "verstalocal",
"ClusterId": "cluster2",
"AuthorizationPolicy": "customPolicy",
"Match": {
"Path": "/verstalocal/{**catch-all}"
},
"Transforms": [
{"PathPattern": "{**catchall}"},
{ "PathPrefix": "/verstalocal" }
]}
or "cluster2": {
"Destinations": {
"cluster2/destination1": {
"Address": "http://127.0.0.1:5555/verstalocal"
}
}
} |

"Path": "/verstalocal/{**catch-all}"
},
"Transforms": [
{"PathPattern": "{**catchall}"},
{ "PathPrefix": "/verstalocal" }
]}That combination ends up with the same result as if you didn't have any transforms. What url is the site redirecting to? This "/verstalocal/" prefix might not be a viable option when working with your destination server. There's only so much the proxy can do to fight what the destination wants to do. |

With the current config Url: Do you think that is not a good approach to include the prefix? Best regards and thanks for your time! |

Hi @cesamej - Did you resolve this and how? Sorry it wasn't clear to me. I have the same problem and "PathPrefix" isn't working where I get a 404 for both static files and when i navigate to a different page. Initial load is fine because of the Match->Path which is something like "sit/{**catch-all}" in my example and subsequent requests to other pages (or static files) don't include "sit" in the path and hence fail |
