in reply to Decode perl cgi response in C

By 'receive "Download" when I post to the cgi.... ' do you -- by any chance -- mean that when you do some sort of submit that you are prompted to "Download" something -- as, for example, your cgi script?

If so, you may have a permissions problem or a mis-configured Apache or cgi-bin.

If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post.

    Yes...I think what it is telling me is to download a small file containing the text response. I tried an example in firefox and I got a prompt...Do you want to download test2.cgi? When I downloaded the file, it contained the desired text. "Hello". With my embedded system, I don't want to download a file...I just want to read the text it contains. Is that possible? I have a small perl client that just prints the response, so I would like to replicate this in C.

      Maybe you want to learn about "sockets"? I assume that Unix Network Programming still is the authoritative book about this.

      Basically, a "socket" is like a "file", except you can't seek on it, and it goes over the network. From C, you can read/write the socket and you only need to know about the protocol that is spoken over that socket.

      The basic idea is that "download data" vs. "read data" is only a frontend issue and exists only for users, not for programs.

[Dumu]: Can't rememeber how to correctly tag other monks in chat
[Dumu]: hello jedikaiti
[Dumu]: got it. Anyway. Perl question. Can you use binmode more than once with an open filehandle to read a file first in binary mode, then in utf8 mode?
[ambrus]: Dumu: you can use binmode multiple times, but mostly at the start before you read things. it would be strange to change the io layers after you've already read things, and might not work too well.
[ambrus]: Dumu: why would you want to read the same file both in binary mode and utf8 mode?
[Corion]: Dumu: Yes, but switching needs to be done with caution, as you might read half an UTF-8 character in binary mode, and then switch to utf8 mode...
