Dear all, I found that when I use libwww to download a web page from some particular web site, something like the following happened (not happend everytime, but on occasion): > Write Socket got EPIPE > Error....... Add 73 Severity: 1 Parameter: `Error number not translated!' Where: `NETWRIT > E' > Host recover 0x10b2804 recovered 1 times. Moving 21 Net objects from pipe line to pending > queue > Event....... No more events registered for socket 10 > Event....... Socket 10 unregistered for HTEvent_READ > Event....... Couldn't find socket 10. Can't unregister type HTEvent_WRITE > Host recover Resetting net object 0x100c890 > HTTP Clean.. Called with status -904, net 0x100c890 > HTTPGen..... ABORTING... > HTTPRequest. ABORTING... > Buffer...... ABORTING... > FileWriter.. ABORTING... > Host recover Resetting net object 0x100ce2c But when I called the following function before, the problem seems gone. HTTP_setConnectionMode(HTTP_10); Does it mean that if I do not call this function, libwww can only support HTTP 1.1 server (or partially support 1.0 server)? Can I configure it such that it can auto-select HTTP 1.1/1.0? More detail log (partial) are as follow: ........
