Re: Reg: Header Parameters in IWS

Hi!

This article should help. I ran into this issue a while back and put this
together... there is some apache/config needed. There is also a link to a
Stack Overflow article that goes deeper.

Hi All,

I am stuck with Header Parameter value retrieval using IWS. It would be a
great help if some one provide me some lights to proceed further.

As per the IWS manual "HTTP headers indicates what transport headers (e.g.
HTTP headers) to pass to the web service
implementation code. Transport headers are passed as environment variables.
The environment variable
name for HTTP headers is made up of the specified HTTP header prefixed with
HTTP_, all upper-cased.
For example, if Content-type is specified, then the environment variable
name would be
HTTP_CONTENT-TYPE. If an HTTP header was not passed in on the web service
request, the environment
variable value will be set to the null string."

So I created a new HTTP Header in the IWS Step 7 (Specify Transport
Information to be Passed) as HTTP_X-REQUEST-ID

I am passing the header parameter from client as (X-Request-Id = 123456789)

So here my assumption is, an Environment Variable will be created with name
HTTP_X-REQUEST-ID with value as 123456789. When try to fetch the
Environment variable value in my RPG program i am getting the value as
NULL.

Am i missing something in this? Or any PTF's needs to be applied to support
this? My iSeries version is V7R3.

Could you please let me know your comments on this one?

Regards,
Surender K
