Rebase Delta

Optimization Threshold

(%)

Enter the delta threshold, expressed as a percent, when rebasing is to be triggered. This entry

represents the size of a page delta relative to total page size, expressed as a percent. This entry

triggers rebasing when the delta response size exceeds the threshold as a percentage of base file

size.

Valid entries are 0 to 10000 percent.

Rebase Flash Forward

Threshold (%)

Enter the threshold, expressed as a percent, when rebasing is to be triggered based on the percent

of FlashForwarded URLs in the response. This entry triggers rebasing when the difference

between the percentages of FlashForwarded URLs in the delta response and the base file exceeds

the threshold.

Valid entries are 0 to 10000 percent.

Rebase History Size

(Pages)

Enter the number of pages to be stored before the ACE resets all rebase control parameters to zero

and starts over. This option prevents the base file from becoming too rigid.

Valid entries are 10 to 2147483647.
