One possibility: the module Net::HTTPS, used by LWP::Protocol::https::Socket, uses one of IO::Socket::SSL or Net::SSL.

It chooses by looking to see if $IO::Socket::SSL::VERSION is defined (ie the module's already loaded) and uses that if so.

If not, it first tries Net::SSL, then IO::Socket::SSL only if that can't be loaded.

Outside of mod_perl, you'll get Net::SSL. Inside of mod_perl, if you are using IO::Socket::SSL elsewhere (and I know we are, since I know the code in question ;), you'll get it instead.

This happened to me once before, but at the time I didn't have the ambition to find out _why_ it didn't work when IO::Socket::SSL was used by the module. I just hacked around it (set $IO::Socket::SSL::VERSION to undef just long enough to fool it into using Net::SSL) and went on my way.

to format your post; it's "PerlMonks-approved HTML":

  • 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.
