I need to "pack" a URL into a URL as one of the parameters to a script. For example: 

http://cgi3.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=SignInWelcom
+e&userid=userid&pass=pass&keepMeSignInOption=1&ru=http%3A%2F%2Fcontac
+t.ebay.com%2Faw-cgi%2FeBayISAPI.dll%3FReturnUserEmail%26requested%3Du
+ser%26de%3Doff%26iid%3D1733367971%26frm%3D284%26acceptcookie%3D1%26lo
+ginconfirmed%3D1%26pass%3D%7B_pass_%7D%26userid%3D

If you look deep into the URL, you see the parameter "ru". That parameter has to be an encoded url.

I know that string as a literal would work fine.

So what's my problem?

I want the "ru" parameter as a separate, readable string in perl, so developers don't kick themselves when they look at my uncommented.

Code: 
$main_request = "http://cgi3.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICom
+mand=SignInWelcome&userid=userid&pass=pass&keepMeSignInOption=1&ru=";
$ru = "http://encode_this/";
# Encode $ru ?????
$main_request += $ru;

# Send $main_request

Thanks for the help.
