in reply to CGI: List all params

It's right there in the CGI documentation (perldoc CGI):

FETCHING THE NAMES OF ALL THE PARAMETERS PASSED TO YOUR SCRIPT: @names = $query->param If the script was invoked with a parameter list (e.g. "name1=value1&name2=value2&name3=value3"), the param() method w +ill return the parameter names as a list. If the script was invoke +d as an <ISINDEX> script and contains a string without ampersands (e.g. "value1+value2+value3") , there will be a single parameter name +d "key- words" containing the "+"-delimited keywords.
90% of every Perl application is already written.

[ambrus]: So that, or if you really want something agnostic to the loop, then use curl multi. Its interface is quite reasonable (unless you use an old version),
[ambrus]: though it's very C-like (serious use of varargs so easy to pass the wrong type), and there are some minor problems (busy loop because it doesn't use the same timer as your event loop, so you have to artificially delay timer callbacks by a small amount).
