I insert this post to complete the precedent:

rm258.fav.usu.edu - - [31/May/1995:09:03:23 +0600] "GET / NEI.HTTP/1.0" 302 396

The Present fields in a line of a common log are:

1. Identification of the Host that asks for a file from the sever Web ( rm258.fav.usu.edu )
2. The consumer's identification in base to the username according to the RFC 931. This field is very rarely used for which is represented often by a hyphen (as all the omitted fields)
3. Authentication of the User, used for the protected areas of the site. unless the site doesn't have a protected area from password, in this point a hyphen will appear.
4. Time Stamp ( [31/May/1995:09:03:23 +0600] ): the date and the time when someone has asked for a file server.
5. In demand http ( "GET / NEI.HTTP/1.0" ): it can serve to determine three things: the method used by the remote client to ask for the information, the demand file and the version HTTP of the client.
6. The code of state (302 ) it points out if the file has correctly been sent, if it has not been found, if a copy of the cache has been used and very other.
7. Volume of transferred data (396 ): It points out the number of Byte moved to the client to answer to the operation. in its extended version the log of access of a server web can also record the type of browser and used computer and the site of origin.
