Salut tout monde,
J'essaye de load balancer un site .net sur 6 serveurs IIS avec nginx (CentOS7).
Lorsque j'attaque directement les IIS le site est OK (HTTP 200), mais lorsque je passe par nginx j'obtiens une erreur 404 à chaque fois.
**Voici les headers du site quand je passe en direct** 
 
```sh
Request URL:http://www.mywebapp.fr/
Request Method:GET
Status Code:200 OK

```
**et voici ma config nginx avec laquelle j'obtiens que des 404**
```sh
 upstream mywebapp {
 ip_hash;
 server 10.236.10.21:80;

 }
 server {

 }
```
