[Snort-users] "uricontent" and "offset" notion

Hi All,
I need a little clarification about "offset" modifier notation in conjuction 
with "uricontent" keyword. Does Snort treats "offset" differently in case of 
"uricontent" keyword.

In case of "uricontent" keyword, does snort treats "offset:0" from the start of 
URI, and not from the start of the payload.

The snort manual says that the "offset" tells how many bytes to skip before 
starting looking for the specified "content" keyword and "offset" is calculated 
from the start of payload.

For example: 
content: ".html"; offset:4; would mean start looking for ".html" after 4 bytes.

However, in case of "uricontent" keyword

Will uricontent: ".html"; offset:0; depth:5; would mean start looking for start 
of URI and in next 5 characters. Or it will mean, start looking for ".html" in 
first 5 bytes of payload.


Any help will be appricated.

Thanks,
