I am creating a small internet site for my personal stuff. I want to put there a few links to e.g. FTP resources or SVN server.
The important thing is that the FTP server has the same IP address as the page. I don't want to hard-code the address of my site in the link, because I consider this an anti-pattern. Instead, I would like to tell browser that the resource is on the current server, whichever server it is.
Let's say that the current page is https://example.com/stuff/index.html. If I create a tag things, it will lead to https://example.com/things.index.html.
However, if I add a protocol identifier to an URL, it won't work. For example, download will lead to ftp:///files/thingies.tar.gz, not to ftp://example.com/files/thingies.tar.gz.
What magic code should I put in the place of question marks:
download thingies
UPDATE:
I would prefer a client-side solution. My server machine has very low processing power and RAM amount.
In php (server side language code) if you'd like to forward
ftp:///files/thingies.tar.gz
to
ftp://example.com/files/thingies.tar.gz
considering example.com is the domain where your server is hosted, just do
echo 'ftp://'.$_SERVER['HTTP_HOST'].'files/thingies.tar.gz';
or, in your specific case
download thingies

I am making my first web site with OSX; this is an internal website for my company.
When the server start, I load pages from a different location, from the one that OSX server used to create my template site (because I do redirects that go on the same IP address, so the pages of the redirect obscure the ones from OSX server). These pages are served by a product called Buildbot (a CI server).
Now, I load the main page from the python directory on my computer, and I would like to avoid to get all the pages for the server there, to not mix them up with the buildbot pages; so I am trying to use the directory that OSX server created for me.
The issue thou, is that I do not know how to link pages...HTML is something that I forgot with time; but I remember that each site starts from a root directory, so the computer is protected by outsiders that may try to force it.
Now, I assume that my root is where the start page is loaded from (in my case is /Library/Python/2.7/site-packages/buildbot-0.8.8-py2.7.egg/buildbot/status/web/templates/), so if I use an href to link to another page, I can just access to this tree.
Which means that my website should be in a folder in this path? I can't seem to access the site where OSX server created the website resource (which in my case is Library/Server/Web/Data/Sites/mySite/).
Has been so long since when I used HTML, so I am quite rusty on the topic, and would appreciate a lot any kind of hint. The site will not be available outside our internal network, so I simply need to link pages and resources scattered on my server HD, and put them on web pages.
Here's how I understand:
Let's say your web root is /root, but you want to have a href to an html file in /dog, for example. Is this correct?
Assuming so, you cannot link an HTML file that is not in the web root, as the browser needs to be able to access it. If you were using a server-side programming language you could do this, but not with HTML.
I'm hosting my own server for my website, and I would like to store all the resources on my isps ftp instead (like images, scripts and stuff like that) to prevent unnecessary strain on my server, and because my isps network speed ought to be quicker than the service they provide me. Now the fonts and the javascripts work fine, but when I try the following in my css:
background-image:url("-url-");
It does not want to display on my website, and in chrome I get this:
XMLHttpRequest cannot load -url-. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://my-domain-name/' is therefore not allowed access.
What does this mean?
-edit-
Actually it does seem to display, but I don't think it is supposed to. But they load up in a weird manner so I think I might just host the files on my own server after all.
I don't know the format of your URL (I assume you are using http, not ftp to link the image) or the nature of your "IPS's server" but the error suggests it does not allow hotlinking of images (I.e. cross-domain access to the files is not allowed by the server).
What is the service you are using to host the images? If it isn't indended for this purpose and you want to reduce strain on your own server it would make more sense to use a proper CDN service like AWS (they have a free tier I think).
Not 100% sure if this is the right SE site to ask this, so feel free to move/warn me.
If I have a site www.mysite.com with a form on it and define its action as "http://www.mysite.com/handlepost" instead of "/handlepost", does it still get parsed as a local address by apache? That is, will apache figure out that I'm trying to send my form data to the same server the form resides on and do an automatic local post, or will the data be forced to make a round trip, going online, looking up the domain and actually being sent as an outside request?
Apache does not look at this information. It's your browser which does this job.
On the Apache side the job is only outputing content (html in this case), apache does not care about the way you write your url in this content.
On the browser side the page is analysed and GET requests (images,etc) are sent automatically to all collected url. The browser SHOULD know that relative url /foo are in fact http://currentsite/foo - or it's a really dump browser -. It is his job. And then it's his job to push the request to the right server (and to known if he should make a new DNS request, build a new HTTP connection, reuse an existing opened connection, build several connections -- usually max 3 conn per DNS--, etc). Apache does nothing in this part of the job.
So why absolute url are bad? Not because of the job the browser should have to do handling it (which is in fact nothing, his job is transforming relative url to absolute ones); It's because if your web application use only relative url the admin of the web server will have far more possibilities on proxying your application. For example:
he will be able to server your web application on several different DNS domains
(and then make the browser think he's talking to several servers, parallelizing static files downloads)
he could as use use this multi-domain to set up the application for different costumers
he could build an HTTPS access for external network access and an HTTP (without the S) access on a local name for the local network
And if your application is building the absolute url these tasks will become really harder.
dont use absolute URL's . As i feel it will do a round trip in your case as you have used round trip for the action part. so better use releative URL's
This is for a in house system, that is required to be set-up this way.
I need specific web files, for example, all images to be manually pre-installed on a proxy server and never downloaded from the web server.
When the browser request the page, the only thing sent from the web server to the proxy should be the plain html page.
I would then like the images the html page uses, to be grabbed from the the proxy every time, for the complete render to the browser.
Is there a name for this set up? I have seen about caching but I do not even want the images downladed once. In addition, how would the html page know to use the images from the proxy?
How would I set up such a thing? I do not have a proxy server set-up yet so I do not know what platform I will be using, but suggestions are appreciated.
Thank You.
Well, I think that you could, for example, use Privoxy and tell it to redirect some queries for images to a local server or even let it replace the img src=" attribute inline using regexes.
We have 2 different websites. One is xy.com another is xyz.com. The domain xyz.com is redirected to a folder on xy.com\one
This works fine. Now we want a particular link to be opened (for example, www.xyz.com\abc.html). I am placing this file in xy.com\one\abc.html. But when I enter this url, it takes me to home page, instead of abc.html. Though I can open abc.html, by entering www.xy.com\one\abc.html.
I need to open this file, from link, www.xyz.com\abc.html. How to accomplish this??

I think the problem is your slashes are reversed. Did you keep your url's near a strong magnet?
If you are using apache you might want to have a look at mod_rewrite. There are similar methods available for other servers.
Would be good to know which environment you are using (web server and server side language) and if you are applying the re-direct rules in a programmatic way or via server configuration.
To give a serious reply, there could be several things wrong in the redirect.
You have to setup a redirect from the old domain to the new, by using a .htaccess on the old domain, changing the DNS records for the domain, or probably some other alternatives. Which of these have you used?
In case of the second option the receiving server (xy.com) has to accept the incoming domain (xyz.com). When I set my DNS records for a domain to go to a certain server, I have to actually setup the server to accept that domain, usually by "parking" it in Cpanel. Some hosts charge per parked domain, which is why they don't accept the incoming traffic automatically.
Depending on the method used, the receiving server has to be told what to do with the request.
So most importantly: HOW did you set up the redirect? Was it a DNS record? Was it a htaccess on the side of xy.com? Any other methods? (sorry, this isn't really an answer either but it was too long for the comments)
