The other day you were very helpful. Now I have another question. I have a bookmarklet to grab the current URL or I should say host name (without the http:// part - which is ok) like:
javascript:q=(document.location.host); void(open('http://mysite.com/search.php?search='+location.host,'_self','resizable,location,menubar,toolbar,scrollbars,status'));
The problem is that this bookmarklet only grabs the host name like google.com and not the whole address like google.com/sub/page.htm. Is there any way I can left the http:// part out and grab the remaining url?
If you assume that it's http (not https), then the following should work:
q=document.location.toString().substring(7);
Of course, you need to write q instead of location.host in what follows.
If you want to do it more robustly, use the properties of the Location object and concatenate the ones you want.

I am using grails 2.5.5 version, Suppose I am entering url as www.localhost:8080/app-name then it should open the MyHome.gsp, suppose if I give other url ex: demo1.localhost.com:8080/app-name then it should redirect to some login page like login.jsp. How can I do that?
Let me break it up for you :
Suppose I have www.localhost:8080/app-name
suppose if I give other url ex: demo1.localhost.com:8080/app-name
Your app starts here:
Case 1 :/app-name
case 2 :/app-name
The rest of that url is actually DNS and configurating binding tomcat specific or wild card urls to a given application.
So in short you need to filter entire url in the application parse url and redirect in your app accordingly.
You need to then intercept every url with grails 2 there is SecurityFilters which so far as i know works with apache-shiro may also work with spring security.
and within it you need to overall check for something like
URL url = new URL(request.getRequestURL().toString())
String subdomain=url.host
if (subdomain.contains('.')) {
subdomain= subdomain.split('.')[0]
}
that then returns your `demo1` you then redirect it another url if it matches your specific rule.
But as I said you are talking about superficial stuff here as I expressed what the address is or how somone gets to the app has nothing to do with the actual application. This is why IT is big business. Big business not because everyone tries to narrow everything down into one box doing all of this but because when situations likes this happen bigger thinking is needed i.e. do i need a load balancer something like F5 that will split traffic according to a given url and send to another app container that asks for authorisation.
subdomain= subdomain.split('.')[1] in that case then but this leaves room for errors since user could put in demo1.somedomain.com and if that resolves well it is either split by subdomain= subdomain.split('.')[0]
I would do this then
String subdomain=url.host
if (subdomain.contains('.')) {
def splitter= subdomain.split('.')
subdomain= splitter[0]
if (subdomain=='www' && splitter.size()>1) {
subdomain= splitter[1]
}
}
I have two questions here, that I thought there were already asked, but I could not find anything related.
Let's suppose I have the following URL:
http://www.domain.com/folder/page
And I have an anchor like this:
Page2
First:
Of course when it is clicked, it will navigate to
http://www.domain.com/folder/page2
But if the user has this URL:
http://www.domain.com/folder/page/ <-- Note the last slash
Then the anchor will navigate to:
http://www.domain.com/folder/page/page2
The first question is:
How can I avoid this?
And the second question would be:
How to always do this?
I mean that even if the url ends with a slash or not, navigate to:
http://www.domain.com/folder/page/page2
I know I can do this with javascript, but the idea is to keep using the href without using javascript in every case this happens. I also know I can use relative urls starting with / to referrer the root, but I can't in this case because the url has some IDs in the middle that may change.
Your basic problem is that you have two URLs that resolve to the same resource.
Pick one of them to be canonical and redirect from the other one two it using HTTP.
Failing that, use root relative URIs:
href="/folder/page2"
JWebUnit.beginAt:
Begin conversation at a URL absolute or relative to base URL. Use getTestContext().setBaseUrl(String) to define base URL. Absolute URL should start with "http://", "https://" or "www.".
JWebUnit.gotoPage:
Go to the given page like if user has typed the URL manually in the browser. Use getTestContext().setBaseUrl(String) to define base URL. Absolute URL should start with "http://", "https://" or "www.".
So, one says "Begin conversation at URL absolute or relative to base URL", while the other says "Go to the given page like if user has typed the URL manually in the browser". This doesn't help me in the slightest in understanding them (well, specifically the former; the latter makes sense). What's the actual difference between them? Which should I be using, and when?
I finally did manage to find the answer in the source code.
beginAt does two things: start the browser, then call gotoPage with its argument. Thus, you need to use beginAt the first time, and gotoPage subsequent times. (Perhaps if managing multiple windows it has more use; I haven't dug that deeply.)
I use bit.ly to shorten my urls.
My problem - paramters are not passed.
Let me explain I use http://bit.ly/MYiPhoneApps which redirects (let's say) to http://iphone.pp-p.net/default.aspx
Now when I try http://bit.ly/MYiPhoneApps?param=xx this param is not added to the resulting url.
I know I could create an extra "short url" including a paramter - so http://bit.ly/WithParam would result in http://www.mysite.com/somepath/apage.aspx?Par1=yy and so forth.
But what I want is to have a short URL directing to a page - and then I want to add a parameter to this shortened url - which shoul (of course) land at my page.
Is this a shortcome of bit.ly (and others are maybe able to do it) - or does "parameter forwarding" not work with 301 redirections?

There's no technical reason why it couldn't be done. The service would simply have to look at what parameters it is being sent, and then rewrite the target URL accordingly.
The problem is that it's not necessarily well defined how to do that.
Suppose you have the url http://example.com/default.aspx?foo=bar, and it has the short url http://foo.com/ABCD. What should happen if you try to access http://foo.com/ABCD?foo=baz? Should it replace the value, so you get foo=baz? Should it append it to make foo=bar&foo=baz? If we include both, which order should they be in?
The system cannot know which parameters are safe to override and which are not, because sometimes, you DO want both of them in the URL, and it may matter what order things are added in.
You could argue "Well, just don't allow this for URLs where parameters are already present", but there's also the issue that it's going to complicate the process a lot more. Without this, you just lookup a key in a database and send a redirect header. Now, you need to also analyze the URL to check for parameters, and append part of the URL you were called by. That requires more system resources per redirect, which may become a big problem if your service is used very frequently - you'll need more server power to handle the same amount of redirects. I don't think that tradeoff is considered to be "worth it".
As mentioned in comments by rinogo and Jurgen
In Clickmeter
Destination URL : www.yoursite.com?myparam1={id1}&myparam2={id2}
Tracking link : www.go.clickmeter.com/38w2?id1=123&id2=abc
After click : www.yoursite.com?myparam1=123&myparam2=abc
In TinyUrl
Destination URL : http://x.com?a=1
Shorten URL : https://tiny url.com/y6gh7ovk
Shorten URL + param : https://tiny url.com/y6gh7ovk?a=2
Resultant URL : http://x.com/?a=1&a=2
Added space to post tinyurl
URL shortening associates a unique key based on a full URL (parameters and all), so it is not possible to pass parameters to a shortening service.
Typically
http://iphone.pp-p.net/default.aspx?param=10
must produce a different key to
http://iphone.pp-p.net/default.aspx?param=22
'Parameter forwarding' is simply not possible in these kinds of redirects, as parameters are not valid parts of a shortened URL is most (if not all) services.
hi is there a wait to load a full url.?
url= 'http://www.example.com/whatever.php'
$('#selector').load(url); // this way returns null (empty result)
instead of :
url = 'whatever.php'
$('#selector').load(url); // works fine
Some may think whats the difference i want to use this because im using multiple directories. so i could be on a page like...
example.com/dir/
but the dir folder will not have the whatever.php
so anyone has a fix for this that i should always use the full url?
thank you.
You could always use relative paths
putting / before the path will tell the browser to go the root of the page. For your example you could call /whatever.php.
You can also move up one directory at a time. Lets say you are in a page at http://www.example.com/dir/foo/bar.php and want to access something in the dir folder, you could specify ../inTheDir.php to move up one directory or ../../inTheRoot.php to move up two.
This should work for you, but based on your comment it sounds like you have a problem somewhere else since your www. page doesn't seem to respond correctly.
No, there isn't.
If http://www.example.com/ takes longer to load than http://example.com/ then it is probably because you have the DNS record for example.com cached but not the record for www.example.com.
Corrected after having realized a typo changed the meaning of the question.:
This is a case of having a mismatch between the host name the page is loaded from and the host name the Ajaxed resource is requested from. i.e. The Same Origin Policy.
Pick a host name to be canonical, use that one in your requests, and redirect (with a 301 status code) from the other so that people don't go to the wrong one by mistake.
