Ip sla http get

When ip sla w/ http get is configured on a router, does it retrieve the actual payload such as images?
We're about to start evaluating WAN optimization products from a few vendors, and plan on using ip sla to see if performance improves.
If ip sla w/ http get doesn't download the actual web page content, then I'm not sure if it's a valid test, since most of the WAN Op products optimize WAN traffic by caching objects, besides tcp window sizing.

No, it does not. IP SLA will do a GET on the page requested, but it does not recursively grab embedded content such as images, videos, CSS, etc. The web page itself (i.e. the HTML) will be downloaded. It is equivalent to telneting to tcp/80, and running:
GET HTTP/1.0\r\n\r\n
The IP SLA test would still be good to do as it will help you baseline the DNS, TCP connect, and page load times. This could show you whether or not WAN optimization will help. For example, if you see long DNS lookup times, it may be that your DNS is overloaded or too far away.

Using ADFS authentication to perform SSO via HTTP GET request

Hi,
Can i authenticate users (those users are clients, at home) to a web application using ADFS without SAML tokens?
The situation is that i want the clients to perform SSO to the website via a link they receive in their mailboxes.
I thought about a solution that combines JWT in a URL link that each user will get to his private mail. this link will contain the users' claim (such as ID Num, given from AD DS Server dedicated especially for them).
Thus, the user will receive an email with a link that already contains a short period of time JWT to perform SSO to the webapp.
Is it possible ? anybody heard about a similar solution ?

Thanks for your message
Here is the my requirment
The basic flow of a Where 2 Get It REST API call is:
1) create the required XML structure,
2) URI encode it,
3) make a HTTP GET request,
4) then parse the return XML document.
Currently i have some data in ABAP structure with 5 fields, i need to create XML from the those 5 fields,and needs to be URI
encode it, and then needs to make a HTTP get request to connect Where to Get It REST API, finally it will return XML document via HTTP Get request , and then needs to convert the return XML to ABAP structure for further processing .the above 4 points will be implemented in my report.
Any body could help on this

Retrieve data from a non-peoplesoft application using HTTP Get

I need to retrieve data from a non-peoplesoft application. They want us to submit a HTTP GET request to their URL with a series of parameters. I am thinking about using HTTP Targert connector to accomplish this. Does anyone have sample peoplecode?
Currently we are on 8.51.10 Tools...
If there is any better way .. please let me know ..

I have used HTTP Get to get XML file from a government sanction list by hitting URL http://www.treasury.gov/ofac/downloads/sdn.xml
There is a delivered PS program that does that for vendor sanctions. I had to get the online setup correctly by creating a new custom Node with HTTP Target Connector. The program name is BSP_IMPORT. The below code is responsible for the calling the node and retrieving the data. Play around with the code below see if you can get it to meet your needs.
BSP_IMPORT_AET.BANKNODE.Value is just the custom external code that I created.
PMT_FLAT_FILE_INBOUND message is just a none rowset based message to use the web service call.
Local TR:FileUtilities:FTP &oFTPUtil = create TR:FileUtilities:FTP();

HANDLING HTTP "GET" IN SENDER ADAPTER

Hi,
I have a Scenario where I have to use HTTP GET Adapter to get data from a website daily to PI and Post the data from PI to SAP ECC.On the receiver end Idoc is being used.I need help on what to use (From sdn I came to know that Java Proxy or Adapter Module can be used ) and how to configure the sender adapter in this scenario.In case of Adpater module the steps needed to configure the scenario would be helpful.In case of Java Proxy sample code that would suit the scenario would be appreciated.

Only 7.3 version (Latest) supports HTTP GET method. All previous versions support only POST.
In your case java proxy is better choice.
Refer these standard links.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/7d4db211-0d01-0010-1e8e-9b07fc2113ab?quicklink=index&overridelayout=true
http://wiki.sdn.sap.com/wiki/display/Java/JavaProxyChangesinPI7.1fromPI7.0
http://help.sap.com/saphelp_nwesrce/helpdata/en/86/58cd3b11571962e10000000a11402f/content.htm
Basically you have to create java proxy for the outbound (sender) interface and use those proxy(stub) objects to code in java. Refer sender java proxy in the above link.

HTTP GET Error - PI does not allow more than 200 chars in the dynamic URL

Hi Everyone,
Scenario RFC <-> PI <-> HTTP (GET).
PI 7.1, Service Pack 05.
HTTP Setup > URL Address
The response comes back from the target server when stuffing the URL path in the communication channel "Path" field.
/rest?&xml_request=......................................................
The requirement is to dynamically create the URL in the mapping program. While doing this the interface error out saying the URL exceeds the character limit of 200.
Any thoughts on this would be highly appretiated.
Thanks,
AJ

Hello.
Currently the Http receiver adapter is configured as HTTP get . We need to change it to HTTP Post and put the parameters in the URL in the body.
Can someone please give an example on how to conevert a http get to http post. Is it a simple thing to do or does it need some java programming?
Thanks for your help.

HTTP GET request to XI

hi forum,
i have been trying to send a HTTP GET request to XI using SOAP and HTTP adpaters (by designing objects in IR and ID), but failed to do so,
the requirement is specifically sending HTTP GET, (no content in the body)
Is there any way of achieving this using existing adapters,
My observations:
when i make a HTTP GET request to XI using sender HTTP adapter, it gives a response "Body is empty" with HTTP code 204-No content,
when i use SOAP adapter, and make a HTTP GET request to intergration engine, using sender SOAP adapter, it gives a response
<html>

hi prateek..... lot of thanks,
developing/deploying a proxy ejb for this purpose seems good,
but, deploying a custom servlet (for calling that ejb) seems "not-so-standard" way,
since i m very new to custom j2ee development in XI, i have certain queries:
1. Is there any guidelines for developing and deploying custom j2ee components,
2. Will SAP provide support in case of these components not working "as expected" or hampering other applications,

HTTP GET for sender adapter possible ?

I have to get XML-messages from third party webservice. I should use HTTP GET to get the data but is this possible in XI ? I mean like RFC->XI->HTTP(GET) and I would process the response from HTTP GET call.

Hi Jari,
For getting response from web service, you should use SOAP adapter.
Anyways,if it for web application, you can use HTTP get in XI for synchronous communication.
Have a look at these blogs for details -

Retrieving image using HTTP GET method?

I want to send a image to a client browser. My servlet's HTML response to the client browser contains the <img src="..."> tag. The client browser uses the HTTP GET method to call my servlet's DoGet method, and I must transfer the desired image to the client browser in this DoGet method at servlet. Now, the problem is that, what should be the source URL in the image(img) tag that is present in my servlet response to client?
For eg: the img tag should be like this
<img src="http://<hostname>:<portname>/<servletname>/...?[var1=value1]">
Now at the ellipsis that you see in the above source URI, I want to write the type of image file (something.jpg) ,so the browser knows what kind of image file it is.
To sum it up...how to get the image using DoGet method and <img src="...">
Regards,
Amit

To give you a better idea on what's happening, read the RFC:
(HTTP/1.0) http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html
(HTTP/1.1 - compressed data)
http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
If you for example execute the command by telnetting to port 80 on a server:
GET http://somewhere.com/some.jpg HTTP/1.0<cr>
<cr>You will get this header:
Trying 217.22.64.73...
Connected to xxx.xxx.xxx
Escape character is '^]'.

A webserver usually maintains a list of file extensions by which it will determine the correct MIME type to emit, when a resource is retrieved.
The browser reads the header, and decides what to do with it, in combination with (X)HTML markup.

HTTP GET/POST: J2EE Design Strategy w.r.t servlet implementation

I am in process of designing a J2EE application with browser interface. I have thought of having "Front Controller" Servlet for all HTTP-GET requests and "Action Controller" servlet for all HTTP-POST requests.
I have worked this distinction on the basis that GET request maps directly to page being requested and POST request corresponds to action being performed on some page. Here in fact the design is driven by appropriate selection between GET or POST. So all possible requests on the site should get properly mapped to action or page.
Decision of two servlets is merely to divide the load on single servlet. There being well defined logical (page and action) and implementation (GET/POST) boundary, the division seems workable.
Before actually finalizing this decision I need to know any inputs (pros and cons) of this approach.
Further If I start mapping to actual scenerios,
Request for home page,
Request from HREFs,
Request where new transaction is started
will always be GET Requests.
However what about request method (POST or GET) for update employee profile page when emp. id is available already available on first page ??
And further
Is this GET/POST divison always possible ??
Any constraints that any one can see in this mapping ??
Any comments on the update employee profile scenerio - GET/POST - page/action ??
PS: Pl. discard error scenerios for the moment.

how would you direct the GET requests to one servlet and the POST requests to the other?
Wouldn't they need to pass thru' yet another servlet to decide which is which (GET or POST), and redirect them accordingly?
I would have both GET and POST handled by the same single-point-of-entry servlet. For example, not all data is sent to the server via a POST - you can send form data via a GET, using name/value pairs in the url.

R/3 HTTP GET to external supplier - what are the options

Hello all
Our scenario is that we have to connect to an external supplier using HTTP GET to get our order responses in the return structure. I was wondering what the best/easiest way is to do this.
We cannot use the HTTP adapter since that only supports HTTP-POST. Additionally the RFC that lies behind it does not allow query strings in the definition, something we need to use.
we could make use of the HTTP_GET function module in the SFTP function group but how to do it then?
-we cannot create an abap proxy for this since the outbound WSDL contains invalid keywords (choice keyword not supported)
-we probably could use BPM that calls the HTTP_GET.
-we could write an ABAP that calls the HTTP_GET and puts the output into a directory where XI can pick it up.
-I also read that you could write a small java function that does the HTTP_GET . But i have no experience with this.
So what is the best option to accomplish this?
thanks
Tom

From SP15 you may use Adapter-Specific Message Attributes.
To evaluate adapter attributes in the message header of the XI message, set the Use Adapter-Specific Message Attributes indicator.
     If you want missing message attributes to trigger an error message, set the Fail If Adapter-Specific Message Attributes Missing indicator. If the indicator is set and the header for adapter-specific message attributes or one of the set attributes is missing from the message, this leads to a system error (red flag).
If you do not set the indicator, and message attributes are missing, the adapter accesses information from the adapter configuration.
     If you want to use an HTTP destination or URL set by the mapping, set the URL or HTTP Destination indicator. (The indicator displayed depends on the Addressing Type you selected above). If you set the indicator, the URL or HTTP destination set dynamically is called by HTTP.
If the message header does not contain the URL or the HTTP destination, and you have set the Fail If Adapter-Specific Message Attributes Missing indicator, the XI message is set to status System Error. If you do not set the indicator, the URL or HTTP destination defined statically in the communication channel is used.
     If you want to use HTTP Header Fields, set the indicator and enter the fields in Field 1 to Field 6. The fields are embedded in the HTTP request under the names you enter here.
The technical names of the fields are HeaderFieldOne, .... HeaderFieldSix.
     If you want to use URL Parameters, set the indicator and enter the parameters in the fields Parameter 1 to Parameter 6. The parameters are embedded in the HTTP request under the names you enter here.
The technical names of the fields are URLParamOne, c, URLParamSix.
The attribute namespace for the adapter is http://sap.com/xi/XI/System/HTTP.

OSB proxy for HTTP GET servlet

Hello,
I need to create a proxy in OSB that will accept HTTP/GET requests (with ?param1=value1&param2=value2.... parameters).
My goal is simply to forward this request to another servlet in J2EE instance that will actually serve the request and send back to OSB the text/xml response.
Can you please point me to the correct proxy and business service configuration for this?
Our SOA version is 10.3.6 and we have OSB and J2EE servers in our domain.
Thanks

Hello again,
I found the solution so I will share it with you in case someones needs it the future.
I created a business service with Service Type "Messaging service", request message type "none", response message type "text" and Http transport "GET".
I created a proxy service with Service Type "Messaging service", request message type "text", response message type "text". I created a routing node my flow directed to the business service mentioned above. In the routing pipeline request i put the following actions:
1) Assign:
Expression $inbound/ctx:transport/ctx:request/http:query-string/text()
variable queryString
to assign the inbound query string in a variable
2)Insert
expr: fn-bea:inlinedXML('<http:query-string xmlns:http="http://www.bea.com/wli/sb/transports/http"></http:query-string>')
location: as first child
Xpath: ./ctx:transport/ctx:request
in variable: outbound
3)insert
expr: $queryString (created in step 1)
location: as first child
Xpath: ./ctx:transport/ctx:request/http:query-string
in variable: outbound
Now the query string should be redirected properly to your business service/ GET servlet.

HTTP GET only works once

Web UI Builder:
I have a device that responds to HTTP GET messages.
I made a simple vi that uses the HTTP GET String function connected to a string constant and WireShark to monitor Ethernet traffic.
When the vi is first run an HTTP message is sent and replied to.
If the vi is run again the message is not transmitted.
If the HTTP GET message is changed the new message will be transmitted. But not twice.
If LabVIEW Web UI Builder is closed and restarted the message will again be sent just once when run.
Why is the message only being sent once? It's like all outgoing messages are being tracked and only sent once.

I think this is standard (but not always desirable) behavior of the networking stack that Web UI Builder uses. (On Windows, it's basically the built in/ Internet Explorer networking stack). After the first GET request with the same URL, if the server doesn't send no-cache headers, a cached result will be returned.
If you control the server that you're connecting to (and can add HTTP headers), try adding a no-cache header to the GET response. ("Cache-Control: no-cache" is the first one I'd try).
If you don't control the server you're connecting to / that doesn't work, another workaround is to append a query string parameter with a random number or timestamp. With this approach, the GET URL is always changing, so the caching behavior is disabled and the request should always go to the server.
(Something like this appended to the end of the URL:
or, "&n=[timeInTicks]" if you're already using other query parameters)
