Re: Streaming data using Libcurl

Thanks for the response.

Let me clarify the situation a bit more,

What we have is a libcurl client talking and sending data to our server
(Jetty/SOLR). Now as soon as a chunk is posted via curl_easy_perform, SOLR
tries to parse it and errors out in case the data was not a valid csv (not
containing all the required expected csv fields). What we want is Server to
wait for the next chunk which would give the remaining expected fields and
then process that csv.

For example, we wish to send: 1,value1,value2,value3
chunk1: 1,value1
chunk2: value2,value3

I hope this makes things more clear.
