Hi Currently I am using loadrunner 9.5 version.I recorded the script in web(Http/Html).while recording i enable correlation during recording.Now i facing problem on view states.Though I do manual correlation for some view states.I got some values in parameter substitution.but when i replay the following error occurs
HTTP Status-Code=500 (Internal Server Error).
I also had web_set_max_html_param_len("100000");
my web_reg_save_param is as follows:
"LB=name=\"__VIEWSTATE\" id=\"__VIEWSTATE\" value=\"",
(1) Process. The odds are extremely high that you are not checking for valid content pages and then branching your code appropriate to what has been returned.
(2) All State management variables have to be correlated. Not some, but all. Record twice and compare. The items to be handled should become obvious.
(3) Make sure your maximum param length for a correlated variable is appropriate and you are reusing variables as much as possible, or you could get a single virtual user to use a couple of hundred megabytes of memory (depending upon your viewstate size and number)
