I didnt request the whole code, just the first commented line.
Anyway, thanks.

First and foremost, both "${2:-}" are useless, as that would fill an empty variable with... emptyness.
Second, you dont want something in a variable that defines an extra option - if it hasnt been set by the user.

I'll keep the short approach you've had in the first post:
Code:
curl_args="--fail --max-time 3"


case ${#@} in
1)	url="$1"
	exit_msg="connecting to $url"
	;;
2)	url="$1"
	curl_args="$curl_args -x \"$2\""	# The 'inner' quotes needs escape so they are there when the variable is reused
	exit_msg="connecting to $url via $2"
	;;
esac

curl $curl_args "$url"
ret=$?

[[ 0 = $ret ]] && \
	exit_msg="SUCCESS - $exit_msg" || \
	exit_msg="FAILURE - $exit_msg"

echo "$exit_msg"
exit $ret

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
