ICSdroid 1.3:added “send URL” action in edit calendar view uses multiple threads (up to number of CPUs) for synchronizing subscriptions
I did not find a mention in the documentation and just did a quick test to check it out:
icsdroid sends the correct header and works fine with a gzipped reponse.
GET /test.ics map[Accept-Encoding:[gzip] User-Agent:[ICSdroid/1.4.2 (Android/7.1.2)] Connection:[Keep-Alive]]
Thanks for mention it here. ICSdroid uses the http lib of Android.
