Reading from the HTTP filesystem in the branch now works using HTTP-GET requests with ranges: $> ./utils/pdf-filereader --fsys=http --input-file="http://es.gnu.org/~aleksander/web/index.html"; -r Reading from 'http://es.gnu.org/~aleksander/web/index.html'... read 1024 bytes starting at offset 0... read 1024 bytes starting at offset 1024... read 1024 bytes starting at offset 2048... read 1024 bytes starting at offset 3072... read 1024 bytes starting at offset 4096... read 824 bytes starting at offset 5120... Each of the previous reads is a separate HTTP-GET request asking for specific byte ranges. Cheers, -- Aleksander
