Well, the main "danger" is that you could be directed to a site other than the one you felt safe giving your data too. If you hit a post to Amazon's order form and the last page redirected you to Barnes and Noble's page for the purchase. Worse, if the error document of the site was "tweaked" and the CGI removed you might wind up pouring your data into someone else's logs.

Also, please don't confuse redirect AFTER post with redirecting THE post. You shouldn't be conned into sending data to someone you didn't expect. Where the browser goes after the data is received properly is something else entirely.

Read for yourself: RFC 2616 Sec 10.3.2 and and you might look at most of Sec 15 as well.

• 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.
