Thanks. I missed the NGX_HTTP_SUBREQUEST_IN_MEMORY flag in my first
implementation.

What I don't understand: If I don't set NGX_HTTP_SUBREQUEST_IN_MEMORY,
then the response from the subrequest will be forwarded to the browser,
if I set NGX_HTTP_SUBREQUEST_IN_MEMORY flag, it will not. Is this the
supposed behavior or only a side effect.

A second question: I get the content of the response via

if (r->upstream)
{
ctx->response.len = r->upstream->buffer.last -
r->upstream->buffer.pos;
ctx->response.data = r->upstream->buffer.pos;
}

Question: Will this buffer be available until the end of the main
request or do I have to make a copy here?

Mirko
