Revision 1.46, Tue Feb 2 12:58:42 2021 UTC (3 years, 4 months ago) by robert
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, OPENBSD_7_2_BASE, OPENBSD_7_2, OPENBSD_7_1_BASE, OPENBSD_7_1, OPENBSD_7_0_BASE, OPENBSD_7_0, OPENBSD_6_9_BASE, OPENBSD_6_9, HEAD Changes since 1.45: +2 -1 lines
introduce support for sending the If-Modified-Since header while
fetching over http(s) and use the timestamps from the remote server's
Last-Modified header if available when saving local files
this makes it possible to mirror files better with ftp(1)
the new timestamp behaviour can be disabled with the new '-u' flag
ok sthen@, input from sthen@ and gnezdo@
