I came across a post on Quora addressing why LinkedIn uses tokens like *1_*1_*1_*1_*1_* in their url. The answer mentioned these help track where a user came from to enable a user to return to where he came from.
How exactly does the URL store that type of information, and why would they use that token instead of something more conventional, such as ?last=this-page?
Appears that those are used to carry forward and populate the form values on the left for the search page. The 1 is probably a section or form number, * means wildcard (empty on form). The _ is just a separator. Try populating a previously empty form field and click search You'll you see one of the previously *1 portions of the url be replace with the value you provided in your form.

I have been banging my head over this for the past 3 days (No kidding!!!)....It seems like a very simple thing but I am just unable to do it. So I'm putting the question out here, and am open to any method which would work.
BACKGROUND : An advanced search form on submission used to generate an URL too large for the server. So the form had to be submitted via POST. So far, so good. Form submitted successfully, and the result was displayed. Only remaining problem was pagination.
As it's a POST call, it ruled out will pagination. While will-pagination merges param page to the existing params, but the problem is that it shows on url which results in the same error.
QUESTION: So is there any way, if the user clicks a link NEXT, I can
a) Update the page param
b) Keep the existing params
c) While not changing the URL
d) Transfer control back to the action in controller?
The only solution so far suggested was have a hidden form, repopulate it's value and submit again. The form's pretty complex, so if there is a cleaner way I'd like to know.
I see what you want from your comment. So editing my reply accordingly. You want the information as to which column is being selected in the sort to be available to the controller without having that information available in the url string, and you want to use GET for this not POST
The challenge you have is that you want to preserve state between requests and you need a mechanism for doing this. POST preserves that information by sending it in the body of the POST request. GET does this by allowing you to populate the query string. The other method for preserving state is to use a cookie.
You can manipulate the url with javascript on the page. There are tutorials online for that.
But if you just want a simple controller hack as you say in your comment then the simplest one I can think of is to allow the user to make the GET request to the url with the query params in it, then handle this request in two steps - step one saves the query information to the cookie, step two redirects them to the url with that query string data stripped, and you look on the cookie to see if it has those fields before building your data for that page. It's hacky but it works.
def sort
session[:sort] = params[:sort]
redirect_to url_without_the_query_string
end
There is also the new html 5 feature:
window.history.replaceState(“Replace”, “Page Title”, “/mypage”);
from this stackoverflow answer here: How to remove query string from url using javascript
However I'm not sure I'd recommend messing with the url after load like that (I don't know enough about that solution so I'd recommend you read that answer and see if that fits). So, if you MUST lose that data from the url string, because you need to somehow pass it between requests you either have to use POST, or use the session cookie/redirect method I describe above.
Does your html <form> have an action attribute? If not, add one that points to the page.
If you want to preserve the current GET params so that results from the POST can use , you will also need to modify the javascript triggered on the heading links so that as well as (or instead of) modifying the query string, they write the same data to hidden form fields (which of course then get posted in the body of the request). Your JS library may already include helpful functions for that.
I've searched a lot to try and solve this problem, but I'm not quite sure what to search for. I didn't really manage to find anything.
Essentially I'm working on a website in which users can register for an event. However, if the user is not logged in, I need to redirect them to the registration screen. This much I've been able to accomplish without much difficulty. However I need to redirect back to the event that they attempted to register for.
My real problem is that the URL of the page I need to return to contains an a parameter, and I'm not sure how to make the registration page take that parameter into account when it redirects back.
Currently when an anonymous user tries to go to
http://[...].com/drupal/?q=civicrm/event/register&id=6
I have it redirect you to
http://[...].com/drupal/?q=user/register&destination=civicrm/event/register&id=6
However, once the form is submitted the "&id=6" is not taken as part of the destination parameter, which means you just go to.
http://[...].com/drupal/?q=civicrm/event/register
Which is not a valid page.
Is there a way for me make the destination parameter include "&id=6"?
On a whim I've also tried.
[...]destination='civicrm/event/register&id=6'
[...]destination="civicrm/event/register&id=6"
[...]destination=civicrm/event/register#id=6
You need to url-encode the value for your destination. Try this:
[..]destination=civicrm/event/register%3Fid%3D6
%3F is hex code for question mark (?), %3D is code for equals (=).
It seems a little odd to my, but although everybody knows about the new google search urls (see Google using # instead of search? in URL. Why?) no one has a problem with the HTTP_REFERER.
I'm using the referrer to parse the google string for the searchquery (&q= ) but as this is all in a hash-tag it wont be sent to the server and all i get is "http://www.google.de/".
So do you know a way of getting the query the user searched for, befor landing on my site?
Due to late-2011 Google security changes, this is no longer possible when the search was performed by a signed-in Google user. See:
http://googleblog.blogspot.com/2011/10/making-search-more-secure.html
http://analytics.blogspot.com/2011/10/making-search-more-secure-accessing.html
Since there are multiple q's in the query string you have to match the "q" parameter globally and take the last one:
/[?|&|#]q=([^&|^#]+)/ig
Get rid of "site:" searches (there are others, but I haven't done them)
/[\+|?|&]?site:([^&|^#])+/g, '');
Then parse the results.
/[\w^'\(\)\{\}]+|"[^"]+"/g
This has been working well for me.
I use grails and I have few registration pages.When user enter few textField values, with "Next" link user have to go to the other page....
After user entered all values data have to be saved.
My problem is that I do not know how to take one page's values from another.
What can I use(sessions, setter and getter methods...) to take all entered values in the last page?
I would recommend looking into Grails Web Flow
There are numerous ways to do it
1) Doing a post back, This will send all your form variables as part of HTTP request and you can then query the params to get the values
2) Grails has got a special artifact which is flash. Once you put anything in flash , its remains till the next request
3) You can use session to retain the values till the session does't expire
Hope that help
I have a share button on my site.
But I need to share link with parameters, and each time parameters will be different (I need to track user who is sharing, etc.)
For example need to share link like http://mySite.com/page?userId=111&someParam=222
I can share this well, but how can I force count to work correct?
if I set
data-url="http://mySite.com/page?userId=111&someParam=222"
data-counturl="http://mySite.com/page/"
I am getting count 0 always. How to get this work?
From http://dev.twitter.com/pages/tweet_button,
"The count box shows how many times the URL has been Tweeted."
Your problem is you simply have the url and counturl mixed up. Change url to the short one, for display purposes - that's the one people will see. Use the counturl for the one with all the parameters, to ensure they go to the right place with the parameters intact.
I suspect the reason your count kept showing zero tweets is because you have a different (unique) url as your primary url each time it is tweeted, so each tweet is the first time that url (including its parameters) was shared.
Twitter now lets you send the url through data attributes. This works perfectly for me and should work for you out of the box!
The button (check out data-url):
Tweet
