I want something like:
"http://www.anyhostname.com" ==> "http://192.168.0.1"
i.e. I want to redirect any request other than "192.168.0.1" to "http://192.168.0.1"
I am using Lighttpd as my webserver and dnsmasq as my DNS server.
I have to wonder if you're doing transparent proxying -- if so, there may be better mechanisms to accomplish what you want to do than literally doing what you outlined as your goal.
But if you want to keep going this route, I think you can use lighttpd's mod_evhost facility to easily use a default site configuration:
General Example:
server.document-root = "/home/user/sites/default/site"
evhost.path-pattern = "/home/user/sites/%0/site/"
If example.org is requested, and
/home/user/sites/example.org/site/ is
found, that path becomes the docroot.
If example.net is requested but no
directory named
/home/user/sites/example.net/site/
exists, then the docroot remains
/home/user/sites/default/site
If you have specific hostnames that you want to handle, you can add them to /etc/hosts and your dnsmasq will serve them. This would work if you had a few hundred hosts/domains that you wanted to handle, but if you wanted to handle everything, then dnsmasq may not be the right tool.
I know that PowerDNS's PipeBackend can be used to easily give the same answer regardless of DNS question; this way, you could easily intercept requests and handle some or all requests specially. This way, you could answer 192.168.0.1 for every request, for some requests, or anything you can program.
Okay, I solved the problem. Posting the solution here back with hope that it helps somebody in the future...
I solved this by modifying the lighttpd.conf file. I added the following inside my lighttpd.conf file:
$HTTP["host"] !~ "mydesiredhostname\.com" {
url.redirect = (
"" => "http://192.168.0.1/"
)
}
Thank you everybody for your time. Cheers!

What is the neatest way to redirect these
http://example.com/test to http://example.com/test/
(It should work no matter what "test" is). I'm new to HAProxy - I have different apache backends. Have it working for URLs of this format http://example.com/test/ but cannot get the other type to work.
Have tried:
(1)
http-request set-path %[path]/ unless { path_end / }
which doesn't load the html page properly - possibly because it's screwing up e.g. the referenced JS files.
(2)
http-request redirect code 301 prefix / drop-query append-slash if missing_slash
from the documentation. I figure I need some kind of slight adjustment to this but don't know where to start with it. Any hints would be much appreciated.
This would potentially best be done at the back-end, since only the back-end has a way to actually know which paths should be redirected. But, it should be possible from HAProxy.
It should work no matter what "test" is
I am skeptical that this is precisely what you need, because then (e.g.) /css/common.css becomes /css/common.css/, which would be wrong.
I'm inclined to think you want something like this:
http-request redirect code 301 prefix / drop-query append-slash if { path_reg /[^/\.]+$ }
Redirect to the same path, with the query removed and / appended to the end, if the path ends with a / followed by at least 1 (or more) characters that is neither / nor ..
This should redirect /test to /test/ and /hello/world to /hello/world/ but it should leave paths like /js/example.js and /images/cat.png and /favicon.ico unaffected.
Deeper nesting should work correctly, too, because regular expressions like this either find a match or don't, and this expression only considers whatever is after the final slash in the path. If it contains a dot or nothing, then there is no match, which seems correct.
I have a static showcase website hosted on S3 and using CloudFront, and an online shop (Prestashop) and a blog (Wordpress), both hosted on OVH servers.
I want to make a hidden redirection on two subfolders of my static website so it acts like my 3 websites are on the same host, using the following pattern :
mysite.com/ --> normal behaviour
mysite.com/blog/ --> myblog.com/
mysite.com/store/ --> mystore.com/
Of course, I need every request to be handled that way, eventually having something like that :
mysite.com/store/fr/1-myproduct.html
returns what
mystore.com/fr/1-myproduct.html
would have returned.
This seems really tricky, since I've found no real solution to my problem, and at this point I doubt it may even be possible to do such a thing.
I considered using a proxy but wouldn't that be like using a sledgehammer to get rid of a fly ?
I have searched for any possible redirection and I was only able to find subdomain/domain redirections...
So my question would be "How can I do that ?"
But right now I'm wondering "Can one do that ?"
P.S : It's my first post ever, I'm used to search for a long time before posting and I always end up finding a solution, except for now. Any suggestion is welcome.
I'll check about proxies since it's my last hope
Wait.
I have a static showcase website hosted on S3 and using CloudFront
CloudFront is a reverse proxy.
Depending on how much flexibility you have with the other two sites, CloudFront can potentially take you where you want to go, combining multiple independent sites under one hostname.
This is done by creating additional origin servers for your distributions and then creating additional cache behaviors, with path patterns matching the additonal paths, such as /blog and /blog/* that send requests to the alternate origins.
There is, however, a catch. CloudFront can't remove the matched pattern, so mainsite.example.com/blog/hello-world, matching the pattern /blog/* will be forwarded to blog.example.com/blog/hello-world -- not to blog.example.com/hello-world.¹ This will require changes to the other sites in order to integrate them in this way.
Unless...
If you already have unique path patterns, no problem, but if the extra sites' content is in the root of each individual site, you see the issue, here. Not insurmoubtable, but still an issue.
Your only alternative will be a reverse proxy behind CloudFront to rewrite those paths and send the requests on to the alternate servers. Truly not a big deal either, since HAProxy, Nginx, and Varnish all offer such functionality and can handle a large number of proxied requests on surprisingly small hardware.
The recently (2017) released Lambda#Edge service allows you to rewrite paths on the fly, as requests are processed, if necessary.
But the bottom line is that the reason you have not found a real solution other than a proxy is that there is no alternative -- every path at a given hostname must be handled in one logical place -- one group of one or more identically-configured endpoints. In the case of CloudFront, the logical place is physically distributed globally.
¹ CloudFront, natively, can actually prepend onto the path before forwarding the request, so requests for mainsite.example.com/bar/fizz can be forwarded to foosite.example.com/foo/bar/fizz by setting the origin path to /foo when you configure the origin. But it can't remove path parts or otherwise modify the path without also using Lambda#Edge. In the scenario discussed above, you would leave the origin path blank when configuring the additional origin servers.
Single S3 bucket with the following behavior :
domain.com-> serves the files from root of bucket
domain.com/blog -> serves the files from subfolder in S3 bucket (this is not default behavior)
How to :
https://aws.amazon.com/ru/blogs/compute/implementing-default-directory-indexes-in-amazon-s3-backed-amazon-cloudfront-origins-using-lambdaedge/
Lambda edge code:
'use strict';
exports.handler = (event, context, callback) => {
// Extract the request from the CloudFront event that is sent to Lambda#Edge
var request = event.Records[0].cf.request;
// Extract the URI from the request
var olduri = request.uri;
// Match any '/' that occurs at the end of a URI. Replace it with a default index
var newuri = olduri.replace(/\/$/, '\/index.html');
// Log the URI as received by CloudFront and the new URI to be used to fetch from origin
console.log("Old URI: " + olduri);
console.log("New URI: " + newuri);
// Replace the received URI with the URI that includes the index page
request.uri = newuri;
// Return to CloudFront
return callback(null, request);
};
Summary of code higher :
lambda edge rewrites the path "/blog/" to "/blog/index.html"
I'm using WM9.8. I want to know how to call a GET REST service with path variable like:
http://localhost:8080/client/1 in webmethod.
I can call POST rest service using pub.client.http. But it dosen't work to GET.
Use String varible called "method" to set type of Http request method.
Just put the path variable in the URL and made a substitution to the path variable
e.g: http://localhost:8080/client/%yourPathVariableHere%
Holy cow this is an old question but I just tumbled across it and I thought I might helps somebody else who does.
URLs in webmethods are fixed to a single value, like /client unless you enable watt.server.url.alias.partialMatching=true
After that, you can simply alias a service to /client and all subURLs like /client/1 are sent to that service. You still have to parse them to get the ID out.
Be careful, though, because ALL sub URLs are sent to the service. So after enabling this flag I get /client, /client/1, /client/1/name all going to the same service. You can see how this can quickly become REST-unfriendly.
Welcome essence of the problem.
We have a path
site.com/seveniry-dlya-turistov/...
(Where ... is the character code specific record (of goods), and in front of it, as you might guess - section of this article)
Those show on site.com website under "souvenirs for tourists" page of a souvenir.
I need to redirect this type:
If there is a request to .../eveniry-dlya-turistov/.. substitute the section title in the name of .../seveniry/..., see if there is a request for
site.com/seveniry-dlya-turistov/elemnet1/
we have to do a 301 redirect to
site.com/seveniry/elemnet1/
Please tell me how to do it, and why does not work like that ...
location /catalog {
rewrite ^/catalog/souvernirs-for-tourists/(.*)$ http://SITE-NAME/suveniry/$1 permanent;
}
Thanks in advance for your help!
Should be something like
rewrite ^/seveniry-dlya-turistov/(.*)$ /seveniry/$1 last;
But you need to test the exact regex since it's hard to do by head without testing. nginx will look for another location block matching /seveniry/$1 to serve content.
I am trying to verify the contents of the http response to find a content "abbb" in it.So my rule was
alert tcp MY_SERVER HTTP_PORTS -> any any(msg:"The page accessed has content abbb";to_client; established; content:"abb";sid:XXXXX; rev:x;)
unfortunately this rule seems not to work. Can anyone please tell if there is some issue with my rule.
For starters you need to fix the to_client part of the rule as this is not valid syntax. You will need to change this to be:
flow:to_client,established;
You can find more on flow here.
If you are just looking for the content "abbb" sent from your server to the client then you just need a simple content match like you have. I recommend using the fast pattern matcher here to improve the efficiency of the rule. So your content match would look something like:
content:"abbb"; fast_pattern:only;
Putting this together, your rule might look something like:
alert tcp MY_SERVER HTTP_PORTS -> any any(msg:"The page accessed has content abbb";
flow:to_client,established; content:"abbb"; fast_pattern:only; sid:XXXXX; rev:x;)
If this still isn't triggering then there is probably something else going on. Since you are just looking for this in the content you need to check your inspection depth in the http preprocessor. There is a server_flow_depth and a client_flow_depth. Try setting these to 0 (unlimited) and see if your rule is triggering after. For example if you had a client_flow_depth of 300 and the content "abbb" didn't come until after 500 bytes then the rule is never going to trigger because snort isn't configured to inspect that far into the payload.
If you have adaptive profiling enabled then you need to add the metadata service for http otherwise the rule won't match http traffic. This would look something like:
metadata:service http;
If you don't use adaptive profiling then it will use the ports in the rule header.
