You should take a look at Apache::Session. It might be what you're looking for.

Seriously, store only a session id in the cookie. Don't store a cleartext user id, and make sure you somehow make it impossible to calculate a valid session id. That is, the session id must be a large number - too large to be brute-forced. The distribution of the algorithm that produces the session id must be flat.

And - of course - make sure the login is performed over an https connection.

Other than that, make sure you properly process anything the users submit through forms or url tampering..

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).
Want more info? How to link or How to display code and escape characters are good places to start.


No such thing as a small change
