I am trying to make a Java (Spring) application which invokes a REST api in a .NET Core application. Everything seems to work in the general case, but now that I am making a POST with an XML string which takes up 80 megabytes on my system, the RestTemplate produces a 404 error code saying "Not found". I have tried to remove the POST size limit in both the .NET Core application (by using the `DisableRequestSizeLimit` attribute in the API controller) and in the Spring configuration (by setting the variable `spring.servlet.multipart.max-request-size` to 200MB in application.properties). Neither of it seems to work. Is there some way to fix this? I am willing to use an alternative to the RestTemplate, if that would make sense. I am using the `exchange` method of the RestTemplate object.
