This is vague and contradictory. Please read "How do I post a question effectively?" and "SSCCE". Most of what follows is pure guesswork in terms of what you actually need. Use of non-interpolating quotes would normally suffice: `$ perl -Mstrict -Mwarnings -E 'my ($u, $p) = (q{W$X}, q{Y@Z}); say for + $u, $p' W$X Y@Z` [download] Use of interpolating quotes would normally cause problems: `$ perl -Mstrict -Mwarnings -E 'my ($u, $p) = (qq{W$X}, qq{Y@Z}); say f +or $u, $p' Possible unintended interpolation of @Z in string at -e line 1. Global symbol "$X" requires explicit package name (did you forget to d +eclare "my $X"?) at -e line 1. Global symbol "@Z" requires explicit package name (did you forget to d +eclare "my @Z"?) at -e line 1. Execution of -e aborted due to compilation errors.` [download] See also quotemeta. What you wrote about the "URI::escape" and (later) "uri_escape" doesn't make much sense. URI has neither an `escape()` function nor a `uri_escape()` function; URI::Escape has the latter. Even my best guess at fixing typos doesn't help: `$ perl -Mstrict -Mwarnings -E 'use URI::Escape; my ($u, $p) = (q{W$X}, + q{Y@Z}); say for uri_escape($u), uri_escape($p)' W%24X Y%40Z` [download] We'll need some clarification on what you're actually doing here. — Ken	[reply] [d/l] [select]

Thank you for revert. Below is what I tried to do, but didn't work, yes that was typo, i meant URI::Escape Is it because i tried escaping IP too, do i really need to escape ip address. `##proxy authentication $PROXY_USER = uri_escape($PROXY_USER); $PROXY_PASSWD = uri_escape($PROXY_PASSWD); $PROXY_IP = uri_escape($PROXY_IP); my $proxy_url = "${PROXY_USER}:${PROXY_PASSWD}"."\@${PROXY_IP}:${PROXY +_PORT}"; ### oh, just realized, looks like forgot to add "http://" +. here before proxy user that's why it failed, can you just confirm t +he same. $ua->proxy(https => "$proxy_url");` [download] Thank you	[reply] [d/l]

I liked to put user names, passwords and email addresses in my script(s) like this: `my ($user, $pass, $mail) = qw(root $ecret someone@somewhe.re);` [download] This works with sigils, but there are problems with e.g. Unicode characters, therefore I now prefer `use Config::Tiny; my $ini = Config::Tiny->read( 'whoamI.ini', 'encoding(Windows-1252)' ) +; my ($user, $pass, $mail) = ($ini->{Main}{user},$ini->{Main}{pass},$ini +->{Main}{mail});` [download] and have the data in a config file like `[Main] user=root pass=$ecret mail=someone@somewhe.re` [download] This has the additional advantage, that you can share your script (or brag with it :-)) without compromising confidential data, and can avoid problems with foreign or other unusual characters (of course, you have to adapt the `encoding(Windows-1252)` part). Plus you don't need to change the script when the password changes.	[reply] [d/l] [select]

Hi soonix, thank you for the suggestion, while reading from the file, uri_escape from URI::Escape seems working fine even for "\". Regards	[reply]

Hi. What did you try exactly?	[reply]

Hi, I used uri_escape method for username and password , like uri_escape(username) and uri_escape(password) and used this escaped values in proxy call like , ua->proxy('http://domain\username@password: ipadress:port'). Thank you	[reply]
