Correlation Issue

In a .Net web applicaiton, a ViewState value need to be correlated. I am getting below error. 

Action.c(325): Error -26377: No match found for the requested parameter "C_ViewState2". Either the specified boundaries were not found in the response or the matched text is longer than current max html parameter size of 90000 bytes. The total length of the response is 86502 bytes. You can use "web_set_max_html_param_len" to increase the max parameter size., Snapshot Info [MSH 1 13]   [MsgId: MERR-26377]

When replay the script, the LB and RB of that ViewState value can be displayed in the response of the request in which correlation is executed.  

Is there anybody know why it occured and any solution?

I am using Vugen 12.53 Patch 4. 

Thank you for your help!

Viewstates can be massive. (Grrrrrr)

It's quite possible that it's just too large to gerab with the default param size.

Try something like this before the other calls to see if it fixes the problem.

web_set_max_html_param_len ("3500000");

i have already set the correlation buffer size (web_set_max_html_param_len) to 90K bytes and the ViewState is 86K

I would manually dig through the response and see if you can find the boundaries yourself. And then take another look at the automatic correlation settings for .net stuff.

I did manualy find out the LB and RB from source file of the run-time viewer from replay.

I tried the correlation rule. I tested the rule by copying the response string, it works. However  when regenerate the script, the rule cannot be applied.
