Newly added feeds are fetched more often than needed

[flisk]

Describe the bug
When adding a new feed to CommaFeed, the feed is fetched in full four separate times as of CommaFeed 4.4.0. Below is the access log of a web server receiving such requests:

192.168.40.10 - - [12/Jun/2024:07:35:35 +0200] "GET /test.xml HTTP/1.1" 200 151431 "-" "CommaFeed/4.4.0 (https://github.com/Athou/commafeed)"
192.168.40.10 - - [12/Jun/2024:07:36:00 +0200] "GET /test.xml HTTP/1.1" 200 151431 "-" "CommaFeed/4.4.0 (https://github.com/Athou/commafeed)"
192.168.40.10 - - [12/Jun/2024:07:36:00 +0200] "GET /test.xml HTTP/1.1" 200 151431 "-" "CommaFeed/4.4.0 (https://github.com/Athou/commafeed)"
192.168.40.10 - - [12/Jun/2024:07:36:00 +0200] "GET /test.xml HTTP/1.1" 200 151431 "-" "CommaFeed/4.4.0 (https://github.com/Athou/commafeed)"

Note the timing of the requests – the first one is sent when the feed is analyzed, while the other three are sent in a short burst when the feed is properly added.

Expected behavior
The feed is only fetched once in full, and subsequent fetches observe HTTP caching semantics.

Environment (please complete the following information):

• CommaFeed version (or "commafeed.com"): 4.4.0

Thanks! I removed one superfluous call already, I'll see what I can do about the other one.

Done! I added a small cache to the http client to prevent short burst of requests to the same feed.
