How to redirect the URL in block expection Apex 4.2
Hi team,
In our application, we wrote this logic as shown below
Before the point of the process of the header: On Load before header.
BEGIN IF (:p1_display_eid) IS NOT NULL THEN SELECT modified_date INTO :p1_modified_date FROM test WHERE id = :p1_display_eid; END IF; exception when no_data_found then --Here i need to redirect URL to other screen end;
Kind regards

You can do it programmatically by using the owa_util.redirect_url method:
BEGIN IF (:p1_display_eid) IS NOT NULL THEN SELECT modified_date INTO :p1_modified_date FROM test WHERE id = :p1_display_eid; END IF; exception when no_data_found then owa_util.redirect(''); apex_application.stop_apex_engine(); end;
However I don't like the various side effects inherent in this code. It is not obvious to a developer looking at the page that executes a process will result in changing session state or the redirect to a different URL. It may involve additional database access, but I think I would prefer to implement this as a conditional branch by using a condition is no SQL, and a later calculation to set the value of the page...

How to access the url of the page referred by using script Idoc?
How to access the url of the page mentioned by using Idoc script...
For example
If the following url (http://myhost/mysite) is called by the end-user, it redirects to the UCM login page.
The page of connection, so I want to get their hands on the referring here (http://myhost/mysite). To do this, I followed the following documentation.
I put IdcAuthExtraRequestParams = referer in
/base_domain/UCM/CS/bin/intradoc.cfg and
/base_domain/UCM/CS/config/config.cfg
UCM server restarted and Http server.
Used < $HTTP_REFERER$ > in my htm file. It does not display anything.
Can I know what went wrong? Is there an alternative way to get this?
@Jon, I saw some variables such as ssOrignialUrl have the information in the console, but they are lost when its consultation: in page.
I pulled out the tracedump to the page itself, which gave me a new variable<$AUTH_TARGET_URL$> that contains this value.
Thanks Jon at made me think so

How to get the url of the window?
I need sitelock my game and I need to check what site it is entrenched in. I can't use the _url property, because who checks just the host.
So I need to know how to check the url of the window, similar to javascript's window.location.href.
If you create a (say urlF()) javascript function in the HTML embed referring window.location.href, you can use:
flash.external import. *;

OSX Apache Server: how to redirect the http request?
Hi all
I have a Mini Mac OSX Server El Capitan running. It already serves some sites. Normal Server Web sites:
-site1.example.com
-site2.example.com
Now, I have installed an application that has its own built-in web server. This application would be normally accessible via http on port 80. However, http on port 80 connections are automatically considered trapped by integrated apache of the OSX Server. Therefore, I now put the web application to run in a different port to apache. I also setup a subdomain, so that users can access this application directly, but they also have to type in the port in the URL - for example, the new web app site is reachable at the:
-myapp.example.com:7117
What I would do, is for users to simply access the application using:
-monappli.exemple.com
I know that there is a way for us to have apache to "Reroute" all requests for a specific to an internal port subdomain automatically, but I don't even know where to start. What are the files we need to configure on OSX Server? How configure us them?
Any guidance would be greatly appreciated.
I had the same requirement and has resolved the way you want to as described below.
- Define the additional app to run on another port
- Create a site in.app using port 80 and the same host name you want to use for the additional application
- Set up a redirection for this site in.app as follows
- Source = /, Destination = http://hostname.domain.com:1234 /, Status = Permanent (301)
Of course, use the correct host name, the domain and port for your situation.
PS. the same approach I have described above also can be used to redirect the corresponding https port 80 or 443 site.

How to get the URL of the server?
I am running WLS server on my machine to host a web application in the ADF. How can I get the name of the server in my bean manged. I don't want to hardcode. The URL is something like that
http:// < machine-My-name >: < port > /epmos/faces/MyApp/MyPage.JSPX
How can I get the part
http:// < machine-My-name > <: port & gt;In JSFUtils, there is a getPageURL method. It will give the full URL of your page. You can play with the URL string to get the part you're looking for.
/** * Method to create a redirect URL. The assumption is that the JSF servlet mapping is * "faces", which is the default * * @param view the JSP or JSPX page to redirect to * @return a URL to redirect to */ public static String getPageURL(String view) { FacesContext facesContext = getFacesContext(); ExternalContext externalContext = facesContext.getExternalContext(); String url = ((HttpServletRequest) externalContext.getRequest()).getRequestURL().toString(); StringBuffer newUrlBuffer = new StringBuffer(); newUrlBuffer.append(url.substring(0, url.lastIndexOf("faces/"))); newUrlBuffer.append("faces"); String targetPageUrl = view.startsWith("/")? view: "/" + view; newUrlBuffer.append(targetPageUrl); return newUrlBuffer.toString(); }

Published by: chir0n on January 27, 2010 12:43Hi ChirOn,
I have no configuration of IIS for me to test this, but this gives a shot:
To redirect requests to another Web site or directory
1. in the services manager IIS, expand the local computer, right-click on the Web site or directory you want to redirect, and click Properties.
2. click on the home directory, virtual directory, or Directory tab.
3. under content from this source should come from, click a redirection to a URL.
4. in redirecting to the zone, type the URL of the directory of destination or of the Web site. For example, to redirect all requests for files in the directory of the catalogue to the NewCatalog directory, type/NewCatalog.Good luck!
Best regards
