CGI accessing files on hard drive

rblampain · 04-27-2007, 05:27 AM

Are there special considerations to be aware of when accessing files on hard drive from a CGI script?

The script is written in pure assembly. The read and write sections work fine when tested as a normal program but work sporadically from the CGI program (called from an HTML form) even though the return of headers (the last step) works well.

Thank you for your help.

Do you mean accessing files outside the root directory of the web server?

No, it is data files in the same directory (for testing purpose) than the CGI script.
I suspect there is no special consideration and my program has a bug.

The problem was permissions. I had forgotten the files were going to be read and written by the user defined in the apache configuration file.
