> By default, we use white space ' ' as delimiter in LogFormat:
> {code}
> <LogFormat>
> <Name = "Cdn_access_log"/>
> <Format = "%<cqhm> %<cquuc> %<pscl> %<psql> %<crc> %<fsi>"/>
> </LogFormat>
> {code}
> Of course, we could use other characters, such as comma(',') or any other
> visible character or string.
> But we found that, the value of fields may contain the same delimiter
> characters, it would case hard to extract from log file.
> So I develop a patch, it will introduce Oct/Hex escape sequences
> representation in LogFormat, for example:
> {code}
> <LogFormat>
> <Name = "Cdn_access_log"/>
> <Format =
> "%<cqhm>\001\002%<cquuc>\001\002%<pscl>\001\002%<psql>\001\002%<crc>\001\002%<fsi>"/>
> </LogFormat>
> {code}
> In the above example, '\001\002' are two characters: '\001', '\002' in Oct
> escape sequence representation.
> This patch now supports two forms(the same with the format in C lauguage):
> * Oct escape sequence:
> {code}
> '\abc': a,b,c should be one of [0-9], and (a*8^2 + b*8 + c) should less then
> 255.
> {code}
> * Hex escape sequence:
> {code}
> '\xab': a,b should one [0-9, a-f, A-F], and (a*16 + b) should less then 255.
> {code}
> {code}
> We can also use '\\' to output '\' character itself.
> {code}
