I am quite new to LoadRunner. I am using the 12.50 community edition and am using the protocol TruClient for web.
What should i do in order to delete the cookies that the LoadRunner has accumulated while doing interaction with browser?
As suggested by tserg42, you could add a separate step inside your "Develop Script" of TruClient for adding the "Utils.clearCookies()" command inside a Javascript action.
Please find the screenshots below for adding the above
Step 1
Drag the marked step on to the script
Step 2
Step 3
Upon clicking the "JS" icon at the right corner, the arguments editor would be available for providing javascript commands. Key in the required commands - "Utils.clearCookies()".
Additionally, you can also check "Simulate new user on each iteration" checkbox from Runtime Settings --> Replay --> Simulate new user on each iteration
I guess you are looking for the function web_cleanup_cookies(). Here is some relevant information I have found about its use:
Return Values
This function returns LR_PASS (0) on success and LR_FAIL (1) on failure.
General Information
The web_cleanup_cookies function removes all the cookies that are currently stored by the for use by the script.
Note: Scripts do not use (access or modify) the cookies that are stored by your browser. Instead, each Vuser uses the cookies that are sent to the Vuser by the server host at runtime. These cookies are maintained only while the script runs. The web-cookie functions (web_add_cookie, web_remove_cookie and web_cleanup_cookies) manipulate these temporary cookies, and do not affect cookies stored by your browser.
This function is supported for all Web scripts, and for WAP scripts running in HTTP or Wireless Session Protocol (WSP) replay mode.
You could try Utils.clearCookies() method. By the way, TruClient API documentation is available online.

Overview
I wish to collect the contents of a browser's address bar opened by a function in a program in C / C++. There are a few threads here which discuss the matter. However, none seems to be helpful to me.
My environment
OS : Windows 7, Windows 10.
Development language : C / C++
My project
I am writing an app in which I need to collect data from a server. The server requires the client to authenticate itself and uses the 2-step OAuth 2.0 protocol for that. I need to make use of a web API developed by a third party.
The following page describes the whole process.
https://apidocs.getresponse.com/v3/case-study/oauth2-authorization-code
However, I only have a problem with the first step : obtain an authorization code from the server.
A highlight from this page explains the process for the first step, the only one that matters here :
Want to see by yourself ? Try this.
I have created an account and registered a bogus app on getresponse.com for testing purpose.
Navigate to the following URL :
https://app.getresponse.com/oauth2_authorize.html?response_type=code&client_id=41979979-c18b-11ea-bb1c-00163ec8ce26&state=xyz
Login with :
Your email : jnj54972#cuoly.com
Password : #Aa11111
On the next screen, Click Yes.
After redirection to the example.com site, the next screen shows the following in the address bar :
http://example.com/receiver?code=<code>&state=xyz
This code in the address bar is precisely what I need to continue with the second step of the authentication when this page is displayed in the browser. Hence the necessity to collect the data contained in the address bar.
You can repeat the operation and navigate again to the same URL: you will not have to login again, and you will obtain another authorization code.
(Note : To test the Oauth 2.0 protocol on getresponse.com, I created an app on 9 July 2020. This account has a validity of 30 days. Therefore, the login credentials mentioned above are likely to expire a month after the date of creation.)
What I have tried so far
I won't go in details or this post may get too long. But I did try numerous 'curl GET' requests with various parameters. No luck : I never get the browser's address bar data with the code in return.
Can someone help ?
Here is a list of ways you could use to accomplish your task:
Hook a function that changes the address bar text in the browser. This can be achieved using remote dll/code injection and have the injected code send back the results to your main process by using shared memory or other interprocess communications methods
Get the memory address of the buffer holding the address bar text (memory scanners such as CE) then actively scan for changes in that address for your desired text which in this case is code=
Create a browser extension that listens for url change events in tabs and have it send the results back to your process using sockets preferably
I have a number of web applications that run for a number of businesses, day in and day out.
The applications are in PHP/MySQL/JS Running on a remote apache server.
For many years, I have performed updates at late night when the software is not in use.
I would like to be able to perform updates to the software during working hours, if possible.
I have many times asked my clients to make sure they shut the software down at night, and close their browsers - but can never guarantee that they have done so.
I have a refresh timer in the JS that trigger a browser to refresh at 11:59. It will happen If the browser is still open.
But I would like able to perform this refresh at any open browser - when I want.
I have mulled over a few ways to do this - including cron and database values that can be read and reset - but:
I wonder if anyone has had success with achieving this?
You want to refresh all open browser tabs that are pointing at your xAMP-ish applications. A few questions:
Does the refresh need to be immediate, or can it be deferred? that is, do everyone's tabs need to be refreshed at the same time, regardless of user interaction; or is it acceptable to wait until the next request from each client, whenever it may be?
Can you schedule the refresh ahead of time (say, with at least 1 session-timeout interval lead-up time), or do you need a method that triggers refreshes immediately?
If you require immediate refreshes, with no ahead-of-time scheduling, you are out of luck. The only way to do this is to keep an open channel for asynchronous updates from the server to the clients, which is hard to do with plain Apache/PHP (see comet, websockets).
If you can make do with deferred refreshes (waiting until a user submits a request), you have several alternatives. For example, you can
expire all sessions (by calling a script that removes all the corresponding server-side session files; found in /var/lib/php/sessions/ in linux). Note that your users will not appreciate losing, say, their shopping-cart contents.
use JavaScript to check a client-side version value (loaded at login-time, and kept in localStorage or similar) against incoming replies from the server (which would load it from a configuration file or a DB request). If the server-side value has changed, save whatever can be saved to localStorage (to avoid the previous scenario), inform the user, and refresh the page.
Alternatively, if you can schedule the refreshes with enough fore-warning, you can include instructions in server-replies that will invoke the refresh mechanism when needed. For example, such replies could change your current "reset at 11:59:59" code to read "reset at $requested_reset_time".
As I understand the problem, you would want control over when the user sees 'fresh' content and when the cached stuff is okay. If this is right,
Add the following in your head content -
<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />
Upon receiving this header, user's browser will automatically fetch a fresh content. And you can flip on/off the above lines to suit your needs. This might not be the most sophisticated way of achieving the desired functionality but worth trying.
There are a lot of things to consider before doing something like this. For example, if someone is actively working on a page, maybe filling out a form or something and you were able to refresh their window, that could create a negative user experience. I believe some of the other answers here addressed some other concerns as well.
That said, I know from working with the Launch Darkly feature flag service that it can be done. I don't understand all the inner workings, unfortunately, but my understanding is that the service uses observables to watch for updates. Observables are similar to promises, except they continuously watch for new changes to their target. You could then force a page reload (or perhaps an alert to the user, prompting one) when the target updates.
I have stop and restart services(Sharepoint Administration & Sharepoint Timer Service)
I cleaned the Configuration Cache by using mentioned steps.
Summary of the steps to clear the timer job:
Stop SharePoint Timer service on all servers in the farm.
Browse to C:\ProgramData\Microsoft\SharePoint\Config{GUID} where the {GUID} folder contains a bunch of XML files and NOT the files with a “.PERSITEDFILE” extension.
Delete all the XML files
Update the contents of the Cache.ini file to just say “1” (without quotes).
Restart the SharePoint Timer service on each server
Reanalyze the issue in Health Analyzer
Does anyone know why this keeps occurring and how I can stop it?
First of all try and check your ULS Logs and see if there is any error that arise.
Secondly try and maybe check the event viewer on your SharePoint server to see if any errors are shown and make sure you have enough disk space available.
and also you might want to check this :Clearing Timer Services
Let me know if you see any error post it here.
hope it helps.
Yotam.
How are cookies matched between DSPs like DoubleClick and DMPs like BlueKai for the purpose of ad serving if browser security prevents 1 party from reading the cookie of another party?
From what I've read, the DSP ad pixel would piggyback on the DMPs container tag so that each time the DMP's pixel is called the DSP's pixel is called. At this point, what information can be passed from the DMP to the DSP that allows the DSP to equate its ViewerId to the DMPs ViewerId?
Perhaps, I'm misunderstanding how piggybacking works. Any help is greatly appreciated
Thanks!
Usually u will place a DMP container tag on the page (well, there are other ways as well, I only list one of the standard approaches), where the first request sent is to hit the DMP and the response is DMP id plus a bunch of redirects from the partners (DSP's pixel link could be one of them. Actually if u are using Bluekai,these seats are biddable through their data marketplace). Then the browser will hit all these redirects with the DMP id. So DSP knows the DMP id to its own id mapping. The responses of these redirects return each unique id of these partners, so DMP can store the mappings as well. A simplified explanination could be found at http://www.adopsinsider.com/online-ad-measurement-tracking/data-management-platforms/syncing-online-data-to-a-data-management-platform/
The param passed by http GET or POST is usually cookie ids, where the actual data syn is usually carried out through real time or more often batch download server to server communication.
Although easily done from my perspective with IIS, I'm a total noob to Tomcat and have no idea how to set static values for cookie contents. Yes I've read the security implications and eventually will access via SSL so I'm not concerned. Plus I've read the Servlet 3.0 spec about not changing the value and I accept that.
In IIS I would simply set a HTTP Header named Set-Cookie with an arbitrary setting of WebServerSID and a value of 1001.
Then in the load balancer VIP containing this group of real servers, set the value WebServerSID at the VIP level, and for the first web server a cookie value of 1001 and so one for the remaining machines 1002 for server 2, 1003 for server 3.
This achieves session affinity via cookies until the client closes the browser.
How can this be done with Tomcat 7.0.22?
I see a great deal of configuration changes have occurred between Tomcat 6.x and 7.x with regard to cookies and how they're set up. I've tried the following after extensive research
over the last week.
In web.xml: (this will disable URL rewriting under Tomcat 7.x)
<tracking-mode>COOKIE</tracking-mode> under the default session element
In context.xml: (cookies is true by default but I was explicit as I can't get it working)
cookies=true
sessionCookiePath=/
sessionCookieName=WebServerSID
sessionCookieName=1001
I have 2 entries in context.xml for sessionCookieName because the equivalent commands from Tomcat 6.x look like they've been merged into 1.
See http://tomcat.apache.org/migration-7.html#Tomcat_7.0.x_configuration_file_differences
Extract:
org.apache.catalina.SESSION_COOKIE_NAME system property: This has been removed. An equivalent effect can be obtained by configuring the sessionCookieName attribute for the global context.xml (in CATALINA_BASE/conf/context.xml).
org.apache.catalina.SESSION_PARAMETER_NAME system property: This has been removed. An equivalent effect can be obtained by configuring the sessionCookieName attribute for the global context.xml (in CATALINA_BASE/conf/context.xml).
If this is not right then I simply do not understand the syntax that is required and I cannot find anywhere that will simply spell it out in plain black and white.
Under Tomcat 6.x, I would have used Java Options in the config like:
-Dorg.apache.catalina.SESSION_COOKIE_NAME=WebServerSID
-Dorg.apache.catalina.SESSION_PARAMETER_NAME=1001
The application I'm using does not have any of these values set elsewhere so it's not the application.
All these settings are in context/web/server.xml files at the Catalina base
At the end of the day what I need to see in the response headers under Set-Cookies: (as seen using Fiddler) is:
WebServerSID=1001
NOT
JSESSIONID=as8sd9787ksjds9d8sdjks89s898
thanks in advance
regards
The best you can do purely with configuration is to set the jvmRoute attribute of the Engine which will add the constant value to the end of the session ID. Most load-balancers can handle that. It would look like:
JSESSIONID=as8sd9787ksjds9d8sdjks89s898.route1
If that isn't good enough and you need WebServerSID=1001 you'll have to write a ServletFilter and configure that to add the header on every response.
