Description

Hello,

We use Xerces to parse and validating xml data.

When XML data contains external prolog ( web-hosted prolog ) like: http://www.w3.org/TR/html4/loose.dtd

Our application hang on BinHTTPURLInputStream::receive(char *buf, XMLSize_t len) because it try to read 1024 bytes from socket without timeout.

After investigation, We found that http://www.w3.org/TR/html4/loose.dtd return a 307 status and ask browser to redirect to https url.

I believe the simplest approach is to change buffer chunck size in BinHTTPInputStreamCommon::sendRequest() : L223 to read only first part of HTTP headers.

Is there any way to configure socket timeout?
