It does not differ anything.
I run script in controller for two users. Second user's file is always 212 kb and it is wrong (it should be 121 kb) . In controller there is not any error but when I look real system, second user's actions are not run.
During file downloading, can correlation parameters be wrong? Can it be about Ordinal value in web_reg_save_param_regex?
The point I do not understand is why first user passes but second user fails in real system.
The new script is attached.
