RE: blockwrite: send: Broken pipe.
I ran the http_url_get_raw version tonight a full 1000 times without problems (all those dsply op codes took a long time!). I think previously I've run something similar against yahoo.com and got many thousands without error.
But using the persistent code, something happens. Did you run the code I sent against one of your web pages? Does it continue to work all 1000?
I ran against a smaller page on a different apache server and got 102 before an error. But the error this time was:
recvresp(): end with err
Debugging the blockwrite tonight, I see that it appears to be called twice per invocation. The first time it is called with GET... (length 74) and the second with 0D0A.
It is the 0D0A that causes the error on the seventh time through. I am not sure how to look further at this point.
I can't debug send() so I don't really know what happened this time through.

Possibly the server is cutting you off?
