Takes some time for embedding to work
On my forums it takes a day or two for the embedding to work. Until then it only shows a regular link. But once it shows up, everything seems to work properly.
At first I assumed it was just my browser cache but even after deleting my entire history/cache it didn't make a change. So, now I'm thinking that it has to do with my server cache. We have a heavy server load on my main site so we leverage a combination of APC and Memcached for our caching needs. I have a feeling that both of those are also caching the forums and until they update their cache it causes the embedding not to work. Of course, I'm only guessing because I don't know for sure how it works.
Do you think this could be the reason why it's taking time for the embedding to perform? And how should I deal with it aside from manually deleting my entire site cache every time someone posts a Youtube link?
