I thought using colons in URIs was "illegal". Then I saw that vimeo.com is using URIs like http://www.vimeo.com/tag:sample.
What do you feel about the usage of colons in URIs?
How do I make my Apache server work with the "colon" syntax because now it's throwing the "Access forbidden!" error when there is a colon in the first segment of the URI?
Colons are allowed in the URI path. But you need to be careful when writing relative URI paths with a colon since it is not allowed when used like this:
<a href="tag:sample">
In this case tag would be interpreted as the URI’s scheme. Instead you need to write it like this:
<a href="./tag:sample">
Are colons allowed in URLs?
Yes, unless it's in the first path segment of a relative-path reference
So for example you can have a URL like this:
https://en.wikipedia.org/wiki/Template:Welcome
And you can use it normally as an absolute URL or some relative variants:
Welcome Template
Welcome Template
Welcome Template
But this would be invalid:
Welcome Template
because the "Template" here would be mistaken for the protocol scheme.
You would have to use:
Welcome Template
to use a relative link from a page on the same level in the hierarchy.
The spec
See the RFC 3986, Section 3.3:
https://www.rfc-editor.org/rfc/rfc3986#section-3.3
The path component contains data, usually organized in hierarchical
form, that, along with data in the non-hierarchical query component
(Section 3.4), serves to identify a resource within the scope of the
URI's scheme and naming authority (if any). The path is terminated
by the first question mark ("?") or number sign ("#") character, or
by the end of the URI.
If a URI contains an authority component, then the path component
must either be empty or begin with a slash ("/") character. If a URI
does not contain an authority component, then the path cannot begin
with two slash characters ("//"). In addition, a URI reference
(Section 4.1) may be a relative-path reference, in which case the
first path segment cannot contain a colon (":") character. The ABNF
requires five separate rules to disambiguate these cases, only one of
which will match the path substring within a given URI reference. We
use the generic term "path component" to describe the URI substring
matched by the parser to one of these rules. [emphasis added]
Example URL that uses a colon:
https://en.wikipedia.org/wiki/Template:Welcome
Also note the difference between Apache on Linux and Windows. Apache on Windows somehow doesn't allow colons to be used in the first part of the URL. Linux has no problem with this, however.

I want to forward this URL
https://demo.example.com/page1?v=105
to
https://www.example.com/page1
It's not working if I set so:
But if I remove the ?v= part, it works:
Is there any way to include the ?v= part in this page rule?
The rule you mentioned works only for that exact URL: https://demo.example.com/page1?v=105. If it has any additional query parameter or even an additional character, eg https://demo.example.com/page1?v=1050, it won't match the rule.
If you need to use complicated URL matches that require specific query strings, you might need to use bulk redirects or a Cloudflare worker.
As you know, in order to have dynamic route in Nuxt.js, we should use Underline (_) before the dynamic name. For example the name of the file should be:
_id.vue
The problem is that I want to write something like article-name instead of id. However, the name of folder which should be:
_article-name.vue
leads to error and breaks the projext. How can I fix it?
Nuxt does not support dynamic route names with dashes.
The dynamic route name (i.e., article-name here) is passed to path-to-regexp (via Vue Router), which requires named parameters to consist of word characters (alphanumeric characters and the underscore).
A potential workaround is to use underscore instead of dash:
_article_name.vue

I am trying to connect to this API endpoint, some parameters such as roomTypes and addOns require more parameters inside them. What should the URL be like?
Here is what I am trying, unsuccessfully:
https://api.lodgify.com/v2/quote/308200/?arrival=2020-10-02&departure=2020-10-07&propertyId=308200&roomTypes=[Id=373125, People=5]&addOns=[]
See image of Documentation
The correct format of parameters are as following:
https://api.lodgify.com/v2/quote/{PropertyID}?arrival={DATE}&departure={DATE}&roomTypes[0].id={RoomID}&roomTypes[0].people={PEOPLE}
It seems like you have space (white space) between Id and People in your URL, an URL must not contain a literal space
I have a question regarding the alfresco FTS/lucene search. It is known that in the search query some special characters have to be escaped, like space (by _x0020_).
But it turned out that if folder's name first chatacter is a digit, it should also be escaped. It can be easily tested in Node Browser by creating a folder, like 123456 and navigate to the parent folder in node browser (in my case I have following folder structure: */2017/123456/):
Primary Path: /app:company_home/st:sites/<some-folders>/cm:_x0032_017/cm:_x0031_23456
^this is 2 ^ and this is 1
If I don't ecape first character of the folder I have 500 error returned.
Why is that, I tried to find something relevant in Alfresco documentation, but didn't manage to.
Alfresco v.4.2.0
Lucene search uses ISO 9075 codification (SQL) like similar frameworks, so we need to encode the path elements. It would be nice if the API hides this requirement like the browser url but you could use ISO9075Encode to do the job.
I have various products with their own set paths. Eg:
electronics/mp3-players/sony-hg122
fitness/devices/gymboss
If want to be able to access URLs in this format. For example:
http://www.mysite.com/fitness/devices/gymboss
http://www.mysite.com/electronics/mp3-players/sony-hg122
My strategy was to override the "init" function of the SiteController in order to catch the paths and then direct it to my own implementation of a render function. However, this doesn't allow me to catch the path.
Am I going about it the wrong way? What would be the correct strategy to do this?
** EDIT **
I figure I have to make use of the URL manager. But how do I dynamically add path formats if they are all custom in a database?
Eskimo's setup is a good solid approach for most Yii systems. However, for yours, I would suggest creating a custom UrlRule to query your database:
http://www.yiiframework.com/doc/guide/1.1/en/topics.url#using-custom-url-rule-classes
Note: the URL rules are parsed on every single Yii request, so be careful in there. If you aren't efficient, you can rapidly slow down your site. By default rules are cached (if you have a cache setup), but I don't know if that applies to dynamic DB rules (I would think not).
In your URL manager (protected/config/main.php), Set urlFormat to path (and toptionally set showScriptName to false (this hides the index.php part of the URL))
'urlManager' => array(
'urlFormat' => 'path',
'showScriptName'=>false,
Next, in your rules, you could setup something like:
catalogue/<category_url:.+>/<product_url:.+> => product/view,
So what this does is route and request with a structure like catalogue/electronics/ipods to the ProductController actionView. You can then access the category_url and product_url portions of the URL like so:
$_GET['category_url'];
$_GET['product_url'];
How this rule works is, any URL which starts with the word catalogue (directly after your domain name) which is followed by another word (category_url), and another word (product_url), will be directed to that controller/action.
You will notice that in my example I am preceding the category and product with the word catalogue. Obviously you could replace this with whatever you prefer or leave it out all together. The reason I have put it in is, consider the following URL:
http://mywebsite.com/site/about
If you left out the 'catalogue' portion of the URL and defined your rule only as:
<category_url:.+>/<product_url:.+> => product/view,
the URL Manager would see the site portion of the URL as the category_url value, and the about portion as the product_url. To prevent this you can either have the catalogue protion of the URL, or define rules for the non catalogue pages (ie; define a rule for site/about)
Rules are interpreted top to bottom, and only the first rule is matched. Obviously you can add as many rules as you need for as many different URL structures as you need.
I hope this gets you on the right path, feel free to comment with any questions or clarifications you need
