Library 4.0D

Patch for better logging

Library 4.0C

Patch for PUT and POST
This patch is rather big but it contains some fixes and modifications that enables PUT and POST to work reliably. If you download the 4.0C version of the distribution then the patch has already been applied. It is basically the difference between versions 4.0B and 4.0C. The main set of differences are:

Library 4.0

Library 3.1

Bug in time stamp on files in FTP directory listings
The Library supports "long" directory listings for FTP Unix, VMS and Windows NT servers with file type, size, time and date etc. However, the time stamp is wrong by one hour for files created when daylight saving time is enabled. The reason is that the FTP module in the Library doesn't know the time-zone of the remote FTP server and hence doesn't know when DSR is enabled or disabled. This is fixed in the next version
Problem with nested HTML tags in the HTML parser
A bug which makes the HTML parser crash if is gets more than 20 nested HTML tags. Thanks to Robert M. Fleischman for pointing this out!

Library 3.0

Problems with redirection
Until now all HTTP servers have sent back a small HTML document with a redirection message going:
	If you can see this message then your browser
	does not support automatic redirection.
However, new severs like Netscape and other servers don't send this and hence no stream should be set up. This confuses the Library and it dumps core.
