    Authentication question

    My simple ASP.NET application displays information pulled from some text
    files. The text files are located in a subdirectory of the virtual
    root.

    I have another .aspx page that lets me add more text files to this
    subdirectory by typing stuff in to a textbox. For this page I needed
    authentication. I do not want to use cookies so I just put a
    username/password pair into the web.config file. A login page checks
    this by using ConfigurationSe ttings.AppSetti ngs, sets an inprocess
    session, and redirects to the input page.

    So my authentication is homebrew, it does not use Forms Authentication.

    This all works fine on my local machine. But when I upload it to my
    hosting company, I get a security exception when it tries to write a new
    text file. I thought the ASP.NET worker process had permission to write
    text files local to the application?!

    I've tried a few different settings in the web.config but no luck. Can
    someone tell me how to fix this?

    Thanks for your help.

      As far as I know, the ASPNET account only has read and execute access to the
      application by default, not write access. Some web hosting companies allow
      you to change permissions of the ASPNET account for your website through
      their online control panel, so it might be possible for you to change this
      setting from there...

      Regards,

      Mun

          you have to add read right for the aspnet user in the machine for it to be
          able to write to the directory. to do that just right on the
          directory ->security and then add the aspnet user and set it to write.

              Both of you guys were right. My hosting control panel let me change the permissions to
              give the ASPNET account write priveledges for the directory. Now it works.

              Funny, I've never tried writing to a file. I've done everything else it seems.
