I am trying to understand a new field "x-acl-added-headers" added in W3C log format of Ironport 7.7 .I have seen the guide but enough information is not given on it.Can any on tell me what exactly this field will contain with an example log and how important it is?
You have to set the custom URL to allow.

That field is to log the custom header for youtube (for edutcation), There is a documentation bug #
CSCzv54395 about this and this why you do not see it under the custom field table. FYI : it shows up as -- on the user guide
Unrecognized header. Use this field to log extra headers in client requests. This supports troubleshooting of specialized systems that add headers to client requests as a way of authenticating and redirecting those requests, for example, YouTube for Schools.
We are in the process of fixing this.
I hope this helps.
Youtube was just an example the feature is implemented for generic use of custom headers. However, the only sites that support this that i am aware of is google and youtube. I hope this helps.
i got your point but it will be good if you can provide example log to give more insight to what header information will it contain exactly.
Where i can find the cosolidated list of different Async OS versions supported by Cisco WSA170 , WSA370 , WSA670?
If anyone have it, please mail me on email@example.com..
