[ic] What is mv_pc?

[vincenker]

Thanks for your clarification. :)
So, a randomized number should be ok for mv_pc, right?
My scenario is that:
System generates <A
href="http://...../basket?mv_session_id=xxxx&mv_pc=xxx&..."> when I use
[order xxxx][/order] tags in templates. But I just want the URL in HREF.
So I have to generate the URL by putting all variables together. 
Is there any other ways to get this?

Best Regards, 
Vincent

It is there to generate unique urls for each page - this is so that your
pages will not be cached (say by a web proxy) and then the cached page
delivered to the user next time round instead of your new, different,
page.
There are some proxies out there which seem to ignore http headers
telling
them not to cache..

You don't need to set / return the value. Just trust ic to come up with
the
right urls, including session id where necessary.
