Hi All Currently we are using CGI scripts for copying the files from one path to another path. While doing this, there is lot of internal changes (i.e. renaming the files, preflight the files). After the full process, the files are copied in another path and will display success.cgi, if any problem in the process, it will move error.cgi. Everyting works fine. But some times the file size is more than 200 MB (more than 25 min), the page automatically expired. Since the IE has some security purpose. Could you please anyone to suggest me, how to solve this problem.
