Thanks All of you with Your great and worthless comments
So please try to work with experience not with code
I have use Module Acme::Enc to secure my source code
This works fine with out thread.
when i use Acme::Enc with the script which work on thread
the program is not able to join thread or threads
So if you have an idea, about this then answer me please
my question is Acme::Enc is safe with threads. Next thing I have worked with Acme::Bleach which originally
exchange characters with invisible character.
Acme::Bleach works fine with perl threads when I convert that code for cgi it wont work.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
