    Default Help me validate or break my conceptions of web technology

    In my head it works like this:

    The browser requests a html document from a directory, then reads it and runs as directed. However, for the browser to be able to retrieve information on their system they must have CGI to handle these sorts of request now I believe one way is to use mysql. Essentially mysql is a C (++ or # not sure) database program. The browser sends the CGI a generic type request for a directory, and if the CGI or database management program reads and allows such a request the browser receives the information.


    Assuming this is right generally, my problem is I don't have the terms to research this properly. Also, I don't know the standards. The only way I can write to my web server is to run a program of my own to listen for request, or to use the same FTP that filezilla does. I guess what I want to know is what are the standards for requesting server information. There must be universal standards for not just requesting information, but inputting passwords etcetera. What are the names of these interactions between CGIs and client side programs; I mean there must be some sort of field/discipline around the interaction there? Imagine all the browsers in different languages trying to communicate to all different types of databases, I wouldn't be surprised if there is a whole scripting language dedicated to the universal interaction between server side clients side programs (like an ASCII).

    browser requests a html document from a directory,
    I'd change that to:
    browser requests the server to read a html document from a directory

    Has CGI be replaced by JSP, etc?

    If you want to look at some very old code that I wrote to learn about servers, take a look at this:

    If you don't understand my answer, don't ignore it, ask a question.

    Apache should also be a good resource for source code, concepts, and vocabulary to help you understand and be able to talk about the topics you're studying. I don't know exactly which of their many client-server program to point you to to answer the questions you've posed, but you could start with Tomcat and go from there.

    Perhaps read up upon HTTP (S)

    I am going to be reading through those and will get back to you when I have digested it. Thanks, I don't know why I didn't think of that where better to start that is the universal protocol I was looking for duh.




    but you could start with Tomcat and go from there.
    I will look into that, especially sense as an avid java user I'm sure I will end up going there (no need to re-invent the wheel).



    If you want to look at some very old code that I wrote to learn about servers, take a look at this:
    http://normsstuff.zxq.net/NormsJavaT...TTPServer.html

    Where is the code that interprets the browsers/clients request? (I've downloaded an am going through your jar).



    Also, for a program like filezilla is there server side components (as in to specifically deal with filezilla's request), or does filezilla simply have a generic communication technique (E.G: it can communicate with standard server CGI)?

    *edit* uses serverside components.

    The questions I wrote above still stand, but I have another one-that doesn't warrant a whole new thread. I was wondering why use a namserver instead of the url one already uses? For example, java.com -> a20-65.akam.net -> 2.22.230.65, why not cut out the middle man and have java.com point to a server that can translate it to its ip address (2.22.230.65)?

    The source is in a zip file.

    The source is in a zip file.
    I know, I unpacked it I was wondering where the code actually interprets request (what class), but I found it thanks, by the way, for this code it is helpfull.

    It's very old and has lots of quick and dirty bits to it that I added to try various things.
    I have used it and still use it for testing and debugging applets and client code.
