I appear to be getting a false alarm on [snort/839]  WEB-CGI finger access
Snort 1.9 FREEBSD 4.7-STABLE

rules says:
uricontent:"/finger"; 
http://www.snort.org/snort-db/sid.html?sid=839

payload has this in it:
GET /f/1040/759/1h/pic.infospace.com/info.xcite/pics/fingersm.gif
'http://63.240.15.147/f/1040/759/1h/pic.infospace.com/info.xcite/pics/fingersm.gif&apos;

Shouldn't /uricontent / finger, basically look for this only?

GET /finger
Not anything with a leading /finger?

snort.conf:
preprocessor frag2

preprocessor stream4: noinspect, disable_evasion_alerts, ttl_limit 0

preprocessor stream4_reassemble: noalerts

preprocessor http_decode: 80 unicode iis_alt_unicode double_encode \
iis_flip_slash full_whitespace
