# Trackback pinging broken?

 * Hi folks,
    I was wondering if TrackBack pings were broken for URLs that POST 
   to a URL with a query string? I looked at the code and saw this: $http_request
   = ‘POST ‘ . $trackback_url[‘path’] . $trackback_url[‘query’] . ” HTTP/1.0\r\n”;
   I think it should be this: $http_request = ‘POST ‘ . $trackback_url[‘path’] .“?”.
   $trackback_url[‘query’] . ” HTTP/1.0\r\n”; note the addition of “?” . I was wondering
   if this was an intentional omission or if this was a bug? I haven’t checked CVS
   yet to see if it’s been fixed. Thanks, Sujal

 * Trackbacks have never worked on my WP blog.

 * They work for me for TB urls that use extra path info like WordPress… instead
   of a combination of Query String and POST data like something I’m testing. Other
   apps work fine with this, btw.

 * WP 1.2. I’ve never really cared, but they’ve never worked. *shrug*

 * Do you have an xmlrpc.php file in your blog directory?

 * “they don’t work” continues to be disingenuous at best. They do work just fine
   on many sites – sorry they don’t work on your site. Instead of posting misleading
   statements (which won’t bring you closer to solving your problem) you could join
   in the search for an answer.
    Sujal, I hope you get an answer to your question.
   If you do elsewhere, please post back here. I haven’t heard of such a problem
   but I will keep an eye for an answer.

 * It may be a php memory_limit issue – that was the case for me. Trackbacks “suddenly”
   stopped working at one point, I tried every suggestion I could find and then 
   upped the /etc/php.ini memory_limit to 32M (.htaccess can be used as well php_value
   memory_limit=16M )….
