I would like to add an authorization to my web site through htaccess.
I added this code :
# BEGIN Cache-Control Headers
<ifmodule mod_headers.c>
Header set Access-Control-Allow-Origin: https://www.example.com
Header set Access-Control-Allow-Headers: Special-Request-Header
Header set Access-Control-Allow-Credentials: true
Header set Access-Control-Max-Age: 240
</ifmodule>
# END Cache-Control Headers
But the website give Internal Server Error when I try to add the line below :
Header set Access-Control-Allow-Methods: PUT, POST, OPTIONS
A special authorization is required or it is a syntax error ?
Try with "":
Header set Access-Control-Allow-Methods "PUT, POST, OPTIONS"
I'm trying to set HTST Header in .htaccess based on kind of request (https or http). I tried to modify this piece of code, which sets header "max-age=300" to image files by checking E variable:
RewriteRule \.(png|gif|jpg) - [E=image:1]
Header set Cache-Control "max-age=300" env=image
This way:
RewriteCond %{HTTPS} on
RewriteRule ^ - [E=STRICT_ENV:1]
Header always set Strict-Transport-Security "max-age=63072000;" env=STRICT_ENV
But seems that STRICT_ENV variable is not set at all.
Give this header a try:
Header set Strict-Transport-Security "max-age=63072000" env=HTTPS
Firstly I tried adding multiple ifmodule but it does not work.
<ifModule mod_headers.c>
Header set Access-Control-Allow-Origin: http://domainurl1.com
</ifModule>
<ifModule mod_headers.c>
Header set Access-Control-Allow-Origin: http://domainurl2.com
</ifModule>
When try to add multiple ifmodule only last one(http://domainurl2.com) works others not.
then I try following code it works but i think it is not secure to allow everyone
<ifModule mod_headers.c>
Header set Access-Control-Allow-Origin: “*”
</ifModule>
I have 5 domain that i have to allow.
Are there any solutions for adding multiple domains that i want to allow?
Try this if you want a quick fix
<ifModule mod_headers.c>
Header add Access-Control-Allow-Origin "http://domainurl1.com"
Header add Access-Control-Allow-Origin "http://domainurl2.com"
</ifModule>
However, this is not the recommended solution by W3C, instead you should make the server read the Origin header from the client, then compare it to a list of allowed domains and finally send the value of the Origin header back to the client as the Access-Control-Allow-Origin header. Check http://www.w3.org/TR/cors/#access-control-allow-origin-response-hea for more details.
I can't figure out why my .htaccess header settings doesn't work.
My .htaccess file content:
Header set Access-Control-Allow-Origin *
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
Header always set Access-Control-Allow-Headers "*"
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]
But when I remove Header's and add them in index.php then everything works fine.
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: *");
What am i missing?
This should work:
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
Just for the record, I was running into the exact same problem and none of the answers worked.
I used a headers checker tool: http://www.webconfs.com/http-header-check.php
I was testing with my IP (http://192.0.2.1/upload) and what came back was the following:
HTTP/1.1 301 Moved Permanently =>
Date => Sat, 10 Jan 2015 04:03:35 GMT
Server => Apache/2.2.21 (Win32) mod_ssl/2.2.21 OpenSSL/1.0.0e PHP/5.3.8 mod_perl/2.0.4 Perl/v5.10.1
Location => http://192.0.2.1/upload/
Content-Length => 380
Connection => close
Content-Type => text/html; charset=iso-8859-1
There was a redirection happening and the AJAX request does not honor/follow redirects.
It turned out to be the missing slash at the end of the domain (http://192.0.2.1/upload/)
I tested again with slash at the end and I got this below. Added a slash in the script too, and it was now working.
HTTP/1.1 200 OK =>
Date => Sat, 10 Jan 2015 04:03:53 GMT
Server => Apache/2.2.21 (Win32) mod_ssl/2.2.21 OpenSSL/1.0.0e PHP/5.3.8 mod_perl/2.0.4 Perl/v5.10.1

Access-Control-Allow-Methods => PUT, GET, POST, DELETE, OPTIONS
Access-Control-Allow-Headers => *
Content-Length => 1435

Use this tool to test if your headers are good and to troubleshoot what is happening.
I have a shared hosting on GoDaddy. I needed an answer to this question, too, and after searching around I found that it is possible.
I wrote an .htaccess file, put it in the same folder as my action page. Here are the contents of the .htaccess file:
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
Here is my ajax call:
$.ajax({
url: 'http://www.mydomain.com/myactionpagefolder/gbactionpage.php', //server script to process data
type: 'POST',
xhr: function() { // custom xhr
myXhr = $.ajaxSettings.xhr();
if(myXhr.upload){ // check if upload property exists
myXhr.upload.addEventListener('progress',progressHandlingFunction, false); // for handling the progress of the upload
}
return myXhr;
},
//Ajax events
beforeSend: beforeSendHandler,
success: completeHandler,
error: errorHandler,
// Form data
data: formData,
//Options to tell JQuery not to process data or worry about content-type
cache: false,
contentType: false,
processData: false
});
See this article for reference:
Header set Access-Control-Allow-Origin in .htaccess doesn't work
Be careful on:
Header add Access-Control-Allow-Origin "*"
This is not judicious at all to grant access to everybody. It's preferable to allow a list of know trusted host only...
Header add Access-Control-Allow-Origin "http://aaa.example"
Header add Access-Control-Allow-Origin "http://bbb.example"
Header add Access-Control-Allow-Origin "http://ccc.example"
Regards,
I activated the Apache module headers a2enmod headers, and the issue has been solved.
Try this in the .htaccess of the external root folder
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
Be careful with doing Header add Access-Control-Allow-Origin "*" This is not judicious at all to grant access to everybody. I think you should user:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "http://example.com"
</IfModule>
I +1'd Miro's answer for the link to the header-checker site http://www.webconfs.com/http-header-check.php. It pops up an obnoxious ad every time you use it, but it is, nevertheless, very useful for verifying the presence of the Access-Control-Allow-Origin header.
I'm reading a .json file from the javascript on my web page. I found that adding the following to my .htaccess file fixed the problem when viewing my web page in IE 11 (version 11.447.14393.0):
<FilesMatch "\.(json)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
I also added the following to /etc/httpd.conf (Apache's configuration file):
AllowOverride All
The header-checker site verified that the Access-Control-Allow-Origin header is now being sent (thanks, Miro!).
However, Firefox 50.0.2, Opera 41.0.2353.69, and Edge 38.14393.0.0 all fetch the file anyhow, even without the Access-Control-Allow-Origin header. (Note: they might be checking IP addresses, since the two domains I was using are both hosted on the same server, at the same IPv4 address.)
However, Chrome 54.0.2840.99 m (64-bit) ignores the Access-Control-Allow-Origin header and fails anyhow, erroneously reporting:
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin '{mydomain}' is therefore not allowed access.
I think this has got to be some sort of "first." IE is working correctly; Chrome, Firefox, Opera and Edge are all buggy; and Chrome is the worst. Isn't that the exact opposite of the usual case?
After spending half a day with nothing working.
Using a header check service though everything was working.
The firewall at work was stripping them
try this:
<IfModule mod_headers.c>
Header set Access-Control-Allow-Credentials true
Header set Access-Control-Allow-Origin "your domain"
Header set Access-Control-Allow-Headers "X-Requested-With"
</IfModule>
It's preferable to allow a list of know trusted host.
If anyone else is trying this, the most upvoted answer should work. However, if you are having issues it could be possible the browser has cached the REQUEST. To confirm append a query string.
To complete the most upvoted answer, I want to add the case whenever the options to the header is not add in a response request, you could add the always keyword from Apache.
In my case i needed to add the access control allow origin in the response of the redirection and not in the result of the redirection.
And a redirection is giving the 302 code status so the header wasn't filled with the correct information.
In this case I needed to add it :
Header always set Access-Control-Allow-Origin "*"
For more information you can check this thread :
Apache: difference between "Header always set" and "Header set"?
Is it possible to apply HTTP header directives based on the URL's query string using an apache .htaccess?
For example, based on this resource http://code.google.com/web/controlcrawlindex/docs/robots_meta_tag.html under the section titled "Practical implementation of X-Robots-Tag with Apache" it says the following .htaccess file directive can be used:
<Files ~ "\.pdf$">
Header set X-Robots-Tag "noindex, nofollow"
</Files>
I'm looking for something along the lines of:
<QueryString ~ "m=_!">
Header set X-Robots-Tag "noindex, nofollow"
</QueryString>
This way the following URL would NOT get indexed by search engines:
http://domain.com/?m=_!ajax_html_snippet
Any hints/tips/clues would be much appreciated. Thanks.
You can try the following in your .htaccess file
#modify query string condition here to suit your needs
RewriteCond %{QUERY_STRING} (^|&)m=_\! [NC]
#set env var MY_SET-HEADER to 1
RewriteRule .* - [E=MY_SET_HEADER:1]
#if MY_SET_HEADER is present then set header
Header set X-Robots-Tag "noindex, nofollow" env=MY_SET_HEADER
