Difference between these three URL's?

Can somebody explain how does it matter to pass different parameters in a url,

e-g

1: www.domain.com/folder1/folder2/file.html?param=9?val=ty5?test
2: www.domain.com/folder1/folder2/file.html#param=93#val=t5y5?test=9
3: www.domain.com/folder1/folder2/file.html&param=9?val=ty5&test=90#poiu

Basically I want to know what do these three characters (#, &, ?) do in the url. I have seen them most of the times? can I use some thing other than that e-g: www.domain.com/folder1/folder2/file.html*param=9_val+ty5@test

  • 1: ? is used for separating back end code to its arguments. Notice the file extension is html doesn't necessarily says that the back end code is in HTML
  • 2: # is used to link to anchors within the html page
  • 3: & is used for separating arguments with other arguments. in this case, the file.html is also an argument itself, while the backend code is the "/", which can be anything. e.g. index.php, default.asp, index.do. it all depends on your URL rewrite.

? indicates the start of the query string
& separates key value pairs of the querystring
# indicates an anchor. Here's more on anchor links.

Note that all three of your urls are incorrect.

Valid url:

http://domain/path/file?name=value&name=value#anc

I notice you've edited your question with an additional question

can I use some thing other than that e-g: www.domain.com/folder1/folder2/file.html*param=9_val+ty5@test

You can use whatever you like in the part of the querystring or anchor as long as it is url encoded.

This Wikipedia article goes in to the detail and gives some good examples.

  • A ? indicates the start of the query
  • A & separates the parameters in the query
  • A # identifies a fragment in the HTML resource to be rendered. It's often used to identify which but if the page the browser should ensure is in view eg a heading etc

? represents that the URL contains QueryString values. & is used to for multiple querystring values. Example

www.abc.com/page?id=abc&pwd=def

and # is new for me I first time saw it.
