meta http-equiv - is it sent as part of an HTTP header, or does the client parse the body for meta tags?

问题 Wikipedia seems to imply that <meta http-equiv> in a web page causes the server to update the response header, but that doesn't sound right to me since the server would have to parse the document before it's sent. That would be fugly. But, I'm having trouble finding much on what does happen when when <meta http-equiv> is used. It seems likely to me that the client parses the page and clobbers anything that was sent in the HTTP header if a <meta http-equiv> tag is found conflicts with the

Facebook open graph meta tags maximum content length

问题 Does anyone know the maximum valid length for each of Facebook's open graph meta tags?

From what I understand, there is no maximum content length for meta tags in general, just recommendations to keep them under certain lengths for SEO reasons. I'd be curious to know if there is a hard limit and
