I think you mean "arbitrary" rather than "random"?
Which in turn means you want to parse the URL. A quick way is probably
IFS=/ read scheme empty server resource <<<$theurl
which leads to
zwget() {
emulate -LR zsh
local scheme empty server resource fd
IFS=/ read scheme empty server resource <<<$1
case $scheme in
(https:) print -u2 SSL unsupported, falling back on HTTP ;&
(http:)
zmodload zsh/net/tcp
ztcp $server 80 && fd=$REPLY || exit 1;;
(*) print -u2 $scheme unsupported; exit 1;;
esac
print -l -u$fd -- \
"GET /$resource HTTP/1.1"$'\015' \
"Host: $server"$'\015' \
'Connection: close'$'\015' $'\015'
while IFS= read -u $fd -r -e; do; :; done
ztcp -c $fd
}
You can probably work out how to support ftp: using the zsh/zftp module.
