❔ HttpClient vs IHttpClientFactory

Hey. I have a few doubts regarding HttpClient, I was reading:

- https://learn.microsoft.com/en-us/dotnet/fundamentals/networking/http/httpclient-guidelines
- https://learn.microsoft.com/en-us/dotnet/core/extensions/httpclient-factory#httpclient-lifetime-management

And I was wondering why the

IHttpClientFactory

IHttpClientFactory

should only be used for

short-lived

short-lived

connections (and what can be considered short-lived, like a few requests between a request flow?) ?

Also, in the context of a pulling service I assume that what I need is

HttpClient

HttpClient

without

IHttpClientFactory

IHttpClientFactory

(and configure

PooledConnectionLifetime

PooledConnectionLifetime

to prevent DNS problems) since it's requesting the same endpoint frequently, right?

I'm thinking in having a singleton

SomeServiceHttpClient

SomeServiceHttpClient

for each endpoint being used in the pulling service. Is there a difference in having it static or as singleton, I kept seeing posts about people having DNS issues with it being singleton?

Thanks
