NimbostratusReg getfield command in Redirection.
Hi
Is there any difference between the below 2 methods ?.
HTTP::redirect "https://[getfield [HTTP::host] : 1][HTTP::uri]"
HTTP::redirect "https:// [HTTP::host] [HTTP::uri]"
I get the same result when i apply either of them on a Virtual Server listening on Port 80 i.e. http://test7883.com is redirected to https://test7883.com as expected.
Is there any specific advantage of using getfield command in the redirection statement.
Thanks,
Yugandhar.

getfield is tcl function and more flexible to grepping exact value in long URL/URI String.
getfield: Split a string on a character and returns the string corresponding to the specific field. The field_number parameter is 1 indexed.
getfield-
HTTP::redirect "https://[getfield [HTTP::host] : 1][HTTP::uri]" --> Here Split String/character is
: -
HTTP::redirect "https://[HTTP::host][HTTP::uri]" --> Its common redirection conditions.
Rest didn't observe difference.
YugandharHi F5_Rock,
-
Here getfield functionality is to split the host part i.e. http://test7883.com:8900 ?.
-
what is the use of field_number in the above case it's mentioned as 1 ?.
I am unable to understand why we need to split the host part when we have to do a https redirection for the http request i.e. we wil redirect the http request http://test7883.com:8900 to https://test7883.com:8900
Thanks,
Yugandhar

as f5_rock explained, getfield command returns a substring of the input string
in your example : the input string is test7883.com:8900
-
[getfield [HTTP::host] : 1] will return test7883.com
this is the first part of the input string with separator : -
[getfield [HTTP::host] : 2] will return 8900
this is the second part of the input string with separator :
-
[getfield [HTTP::host] : 1] will return test7883.com
