[Snort-users] Interpretation of "offset" in context of "uricontent" keyword

Hi All,
I am reposting this question in the hope of getting some replies:

======================================================================
I need a little clarification about interpretation of "offset" modifier in 
conjuction with "uricontent" keyword. 

Does Snort treats "offset" differently in case of "uricontent" keyword?

Does in case of "uricontent" keyword, snort treat "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 highly appricated.

Thanks,
