I have tried enclosing the second expression with single and double quotes, and have tried using various wildcards such as ".", "?", ".*", etc. to no avail.

Any suggestions?

Thank you,

A single equal sign should be all it takes to make the if-fi work.

Code:
if [[ $2 = http:* ]]; then
   command
fi

NAME
uri_urn - URI utilities, URN scheme SYNOPSIS
package require Tcl 8.2 package require uri::urn ?1.1.2? uri::urn::quote url uri::urn::unquote url _________________________________________________________________ DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to handle urls using the urn scheme. COMMANDS
uri::urn::quote url This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its result. uri::urn::unquote url This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters, and returns the modified urls as its result.
