Re: http-api how to properly hit a api end point multiple times.

Jim,

I think all you need to do is open the connection to just the server the
server...

wwComm = http_persist_open(%TRIM(XYZSERVER));

rc=http_persist_req('PUT': wwComm : %TRIM(XYZSERVER) +
'/rest/foo/update?id='
+ %TRIM(XRFRECID8)
: 0 : *NULL : updrecp : 48 : 0 :
%paddr('FILL_BUFFY') :
HTTP_TIMEOUT: HTTP_USERAGENT :
'application/json');

I am trying to optimize this

I have a http api that I need to hit repetitively :

As it happens, I'm in the same boat.

I've got a suite of RESTful web services, running as part of a Tomcat
webapp, on a Google Compute Debian instance (the same one I mentioned
before) that I'm hitting tens of thousands of times, mostly with
http_url_post_raw calls.

The /tmp/httpapi_debug.txt log file tells me that the HTTPS negotiations
are happeing for every single web service call, and I suspect that this
is a significant drag on throughput.

I've already had to use http_persist_open, http_persist_req, and
http_persist_close, but *only* to handle a service that required a PUT
request, and my calls looked like (proprietary information redacted, and
blanks squeezed to fit):

C eval wwComm = http_persist_open(%TRIM(XYZSERVER) +
C '/rest/foo/update?id='
C + %TRIM(XRFRECID8))
C IF wwComm = *NULL
C'open failed' DSPLY
C ELSE
C eval rc=http_persist_req('PUT':
c wwComm : %TRIM(XYZSERVER) +
C '/rest/foo/update?id='
C + %TRIM(XRFRECID8)
c : 0 : *NULL : updrecp : 48 : 0 :
c %paddr('FILL_BUFFY') :
C HTTP_TIMEOUT: HTTP_USERAGENT :
C 'application/json')
c callp http_persist_close( wwComm )

As you can see, the URL I'm feeding the http_persist_open is very
specific to the request that follows. If I'm to use a persistent
connection AS a persistent connection, the URL establishing that
connection would have to be somewhat more general.

Can that be done, and if so, how? Can somebody either point me to an
example, or show me how I would modify the above code?
