[https://www.socsci.ru.nl/tsg/sequence Sequence of URLs] Allows you to send the same data as URL parameters to a numbers of URLs that together make up your experiment. Typically You will start from SONA or Prolific, then go to an informed consent form, then to an online experiment or survey and then back to Prolific for completion of the experiment.

= Simple example =
If you want to visit two URLs and let both know that your name is John, you can visit these pages like this:
* https://www.ru.nl?name=John
* https://www.nos.nl?name=John
But you may want to prevent having to type the same information twice. That is where [https://www.socsci.ru.nl/tsg/sequence Sequence of URLs] can help. Put you two URLs in a sequence:
[[File:Overview .png|border|A sequence of two URLs]]
now you can visit the following two URLs:
* https://www.socsci.ru.nl/tsg/sequence/123456/0?name=John
* https://www.socsci.ru.nl/tsg/sequence/123456/1
which will be automatically forwarded to the two URLs mentioned above. Note that the name is automatically send to both pages, while it was entered only for the first.

The last of the three comes from Prolific:

[[File:Prolific completion.png|border|Form on the Prolific study page showing the completion URL.]]
Since you programmed ''coolExperiment'' yourself you can make sure that the last page contains a link to the completion URL, but to let the informed consent survey know where the experiment is, you have to add it in the first URL like this:

Instead of linking to the informed consent form directly, you link prolific to the first URL in the sequence:

Now all three URLs will receive the prolific PID, study id, etc.
= Privacy =
This method looks a bit like the way the worlds largest privacy breakers work. After all these web pages receive the name of the person visiting them without the participant sending it.
This is precisely the intention, but from it is also very different. Rather than saving a persistent cookie and storing the participants information for later use, we save
only the precise information entered by the participant, store it only on the participants computer and store it only during the session. Therefore no separate cookie notice is required.
You only need to inform the participant that the information of the separate parts of the experiment is combined, like you would do anyway when using a method like [https://www.socsci.ru.nl/tsg/composer/ URL composer].
