What should I do with my headers?

news.answers/waffle-faq

It'll make your life easier and will do the same for people who exchange mail with you. The important thing to remember is that if you put a domain-style address out without being domainized, people will probably not be able to reply to your mail.

You might want to look at the contents of the control newsgroup once in a while to see what control messages you received that Waffle didn't process. There's a program called procc, 'PROCess Control' which will handle control messages for you. Look for procc-NN.

When should I use keyword headers?

ATS FAQ Section 1: The Newsgroup
Including keyword tags in your subject headers is an important way to help readers with limited time choose which threads they want to download or read first.

Contents How do I make Eudora hide all these extra headers?

SpeedGate E-Mail FAQ
Most email programs show a few useful headers (like Subject, Date, From, and CC) normally, and show the rest only when asked.

Why do I get "Can't locate TCL private headers" error when running configure?

Expect FAQ (Frequently Asked Questions)
Expect is looking for tclInt.h which is one of Tcl's private headers. Tcl doesn't install this by default, so Expect tries to find it in Tcl's source or build directory. To explain where that directory is, use the --with-tclinclude flag when running Expect's configure. If someone (your vendor, for example) has supplied you with Tcl but without providing tclInt.h, get a source distribution and install it yourself (or get a binary distribution that includes the private headers).

What does it mean when my CGIs fail with "Premature end of script headers"?

Apache Server Frequently Asked Questions
It means just what it says: the server was expecting a complete set of HTTP headers (one or more followed by a blank line), and didn't get them. The most common cause of this problem is the script dying before sending the complete set of headers, or possibly any at all, to the server. To see if this is the case, try running the script standalone from an interactive session, rather than as a script under the server.
