This question is related to [this question](https://users.rust-lang.org/t/deploying-a-rust-actix-project-on-same-domain-and-vps-as-a-laravel-project/66803). There I asked if it was possible to deploy two applications on the same domain. It is possible using Nginx reverse proxy, but that is too complicated, unstable and results in a barely functioning web-application.
So I decided to include my website, which was previously a separate Laravel project, also in the Rust part of the application.
My situation:
I have a basic website promoting my application. With URLs like:
```rust
example.com/
example.com/home
example.com/about
example.com/contact
...
```
My web-application provides an unlimited amount of businesses a personalized page. Each business has his own subdomain. So:
```rust
businnesa.example.com
businnesb.example.com
businnesc.example.com
...
```
Each business also has their own pages:
```rust
businnesa.example.com/
businnesa.example.com/buy
businnesa.example.com/contact
...
```
The problem I have now: The routes collide!
Business A has his own about page on `businessa.example.com/about`. But my main site also has a about-page on `example.com/about`!
Route code:
```rust
App::new()
.service(web::resource("/about").route(web::get().to(business_about)))
.service(web::resource("/about").route(web::get().to(main_site_about)))
```
How would I solve this? I'd need something like:
```rust
App::new()
.service(web::resource("/about").guard(IS_SUBDOMAIN).route(web::get().to(business_about)))
.service(web::resource("/about").route(web::get().to(main_site_about)))
```
I could also make a function `about_page_check_if_subdomain()` which would get executed on both `/about`-paths. And checks if the `HttpRequest` contains a subdomain. If so, go to `about_page_business_page()` else go to `about_page_main_site()`. But that doesn't sound really solid.
How do I detect if a request is for a subdomain, and if so, give another route then without subdomain?
Thanks!

I solved it the following way:
```rust
.service(
web::resource("/about")
.guard(actix_web::guard::fn_guard(|header| {
url_contains_subdomain(&format!(
"{:?}",
header.headers.get("host").unwrap()
))
}))
.route(web::get().to(business_about)),
)
.service(web::resource("/about").route(web::get().to(main_site_about)))
// Function to check if given url contain a subdomain
pub fn url_contains_subdomain(url: &str) -> bool {
println!("rofl {}", url);
let url = url.replace("www.", "");
let mut split: std::vec::Vec<&str> = url.split(".").collect();
split.len() > 2
}
```
Let me know if someone has a more elegant solution.
