@ -219,6 +219,6 @@ It has a few limitations:
- We can't send megabytes: the body limit for `keepalive` requests is 64kb.
- If we need to gather a lot of statistics about the visit, we should send it out regularly in packets, so that there won't be a lot left for the last `onunload` request.
- This limit applies to all `keepalive` requests together. So we can't cheat it by creating 100 requests, each 64kb.
- This limit applies to all `keepalive` requests together. In other words, we can perform multiple `keepalive` requests in parallel, but the sum of their body lengths should not exceed 64kb.
- We can't handle the server response if the document is unloaded. So in our example `fetch` will succeed due to `keepalive`, but subsequent functions won't work.
- In most cases, such as sending out statistics, it's not a problem, as server just accepts the data and usually sends an empty response to such requests.
