TA-user-agents: Why are some user agents showing as unknown, and how do we add these into the lookup definitions?

It looks like there are a handful of user agents that show up as unknown:

Mozilla/5.0+(iPhone;+CPU+iPhone+OS+7_1_1+like+Mac+OS+X)+AppleWebKit/537.51.2+(KHTML,+like+Gecko)+Mobile/11D201
Mozilla/5.0+(iPad;+CPU+OS+8_4_1+like+Mac+OS+X)+AppleWebKit/600.1.4+(KHTML,+like+Gecko)+Mobile/12H321
Mozilla/4.0+(compatible;+MSIE+6.0;+MS+Web+Services+Client+Protocol+4.0.30319.34209
Mozilla/5.0+(iPhone;+CPU+iPhone+OS+8_3+like+Mac+OS+X)+AppleWebKit/600.1.4+(KHTML,+like+Gecko)+Mobile/12F70

How do we get these added into the lookup definitions? Manually though the .yaml?

One thing you may want to try doing is removing the "+" symbols from the user-agent string (some of the regexes in the YAML do use spaces). Something like:

eval http_user_agent = replace(http_user_agent,"+"," ")

If that doesn't work, then you may need to edit the regexes. This can be done by editing the regexes.yaml, but be aware that those changes may be overwritten on an upgrade.

Close - needed the slash:

eval http_user_agent = replace(http_user_agent,"\+"," ")
