Template fragment caching does not seem to work for some custom template tags

Question

I did caching in my django application and used caching of each view through the cache API and fragment caching. On some of my pages I use my own django template tag, this tag is provided by a third-party developer, it takes some arguments in its template tags, and then makes a request to the remote server, receives a response back via XML and then displays the result on my page. Fine. I thought I could easily cache this using fragment caching, so I:

{% load cache %}
{% cache 500 request.user.username %}
{% load third party custom tags %}
{% expensive custom tag set that gets stuff from a third party server via xml %}
{{ some.stuff}}
{% endcache %}

The problem is what I am doing, requests are still being fired to this remote server, it seems that Django does not like to cache these custom template tags. I know memcached works fine, for other views and templates everything works fine. Am I doing something that is incompatible with fragment caching? Is there any way around this?
