Sending chunked data on intercept plugins
How to send chunked data on Server Intercept Plugin? The content length is
not known before hand. Idea is to stream data as it becomes available. I
am assuming the intercept send data needs to know that the data is chunked.
Any ideas?
Sandeep.

Suppose you begin to write data to the TSVConn which is got from
continuation's handler with TS_EVENT_NET_ACCEPT event, you can insert the
'Transfer-Encoding: chunked' in the response header, and then when you got
a data segment from other place, just wrap it in chunked format.

Thanks,
I was a little confused about this part. I was looking for helper function
which can do it for me. I see that ChunkHandler has access to chunk and
dechunk, but is not exposed. Should this be exposed for making the plugin
experience easier?

You'll have to handle chunking yourself; it should be relatively simple to
do.

Who will be responsible for chunking? Plugin has access to response and not
chunked data. If Intercept writes a raw byte stream, how does the data get
chunked?

The server intercept writes a raw byte stream, so you can do whatever you want. If you want to write a chinked response, just write it as if your plugin was a real HTTP server (which, effectively, it is). Take a look at example/intercept/intercept.cc.
