I want to add a rewrite policy in Citrix netscaler.
/activities/* should go to one server
/activities/*/* should go to another server
So what are the content policies I need to configure in url rewrite of netscaler?
Forget about URL rewrite, it will be a payne. Take a look at the URL Transformation feature on the NetScaler https://docs.citrix.com/en-us/netscaler/12/appexpert/rewrite/url-transformation/configure-rewrite-proxy-requests.html
Note: After you make this work you might need to create additional policies to correct hardcoded links and other things on the source code of your website. It might take quite an effort. good luck

Being new to perfect server side swift, I cannot find any packages that help with role based access authorization. In Spring there is for example,
.antMatchers("/homePage").access("hasRole('ROLE_USER') or hasRole('ROLE_ADMIN')")
.antMatchers("/adminPage").access("hasRole('ROLE_ADMIN')")
Is there something already existing in perfect to help with this? Is there a recommended way of handling access control in perfect?
As you use perfect server, you may take a look at:
PerfectlySoft Perfect-Authentication
perfect.org authentication
perfect.org Turnstile
Perfect provides system level of authentication.
Firstly, you can go to github and search PerfectlySoft/Perfect-LocalAuthentication for user identity validation, however, it doesn't contain the role control as you asked.
It can be done in other approaches. For example, you can use Perfect-LDAP to access an LDAP server for all kinds of roles and groups.
I am uploading images to a public directory and I would like to prevent users from downloading the whole lot using wget. Is there a way to do this?
As far as I can see, there must be. I have found a number of sites where, as a public browser, I can download a single image, but as soon as I run wget against them I get a 403 (Forbidden). I have tried using the no-robot argument, but I'm still not able to download them. (I won't name the sites here, for security reasons).
You can restrict access using user-agent string, see apache 2.4 mod_authz_core for example.
Wget also respects robots.txt directives by default. This should repent any casual user.
However, a careful look into wget manual will let to bypass these restrictions. Wget also lets to add random delays between requests, so even advanced techniques based on access pattern analysis may be bypassed.
So the proper way is to mess with wget link/reference recognition engine. Namely, the content you want to keep unmirrored should be loaded dynamically using javascript and the urls must be encoded in a way that would require js code to decode. This would protect your content, but would require to manually provide unobfuscated version for web bots you want to index your site, such as google bot (and no, it is not the only one one should care about). Also, some people do not run js scripts by default (esoteric browsers, low-end machines, mobile devices may demand such policy).
I got 2 domains bought at diferent providers and I would like http://aaaaa.com to show http://bbbbb.com/aaaaa
Is this possible using only DNS? must I transfer the domain to my hosting provider that has the http://bbbb.com domain? I really don't want to use a redirection or iframe.
Thank you for your help!
You can do that on DNS Level in two ways:
Depending on your Provider you can make http://DomainA.com/ redirect with masking to http://DomainB/Folder now this is premature way of doing it specially if SEO matters to you.
If you have your own servers or you can add Virtual Directory on the server you can point DomainA to this server and make http://DomainB/Folder location as start point.
This can be done with Apache, Nginx or IIS.
Please can you give me more explanations on what OS and what kind of hosting you have so i can help you with this? And also what kind of application because if your using .net its a bit different then using normal PHP or HTML or wordpress... U will need to add Virtual Directory to achieve this.
If your using shared hosting and have Apache web-server the easiest way to do it is so:
.htaccess and Apache also can handle such redirection.

I was thinking about a building a CMS, and I want to implement the wordpress-like permalink for my posts. How do I do that?
I mean, How do I define the custom url structure for my pages?
What language are you using? I'm assuming that you are thinking about PHP (given your reference to word press). You have a few options:
Mod-Rewrite
Router
In my opinion, the best option is to find a modern web framework that provides good routing functionality. Furthermore, look at modifying an existing CMS (many exist; you seem to have heard of word press).
I'd recommend creating links that pass in a URL parameter such as ..."http://...PostID?123&CatID=232&..." so that when the person clicks on that particular link, you can parse the parameters in the URL, and get the exact post based on id, or even do further filtering by passing in other fields as needed.
If you want to build the whole thing yourself, first understand what a front controller is, as it really addresses the underlying issue of how do you execute the same code for different URLs. With this understanding, there are two ways to attack the problem with this design pattern: URL rewriting or physical file generation.
URL Rewriting
With URL rewriting, you would need intercept the requested URL and send it onto your front controller. Typically this is accomplished at the web server level, although some application servers also act as web servers. With Apache, as others have posted, you would use mod_rewrite with a rule that looks something like this:
RewriteRule ^/(.*) /path/to/front/controller.ext [E=REQUEST_URI:%{REQUEST_URI},QSA,PT,NS]
With this rule, the path originally requested with be sent to the front controller as a variable called "REQUEST_URI". Note, I'm not sure the right syntax in PHP to access it. In the front controller hash (e.g. MD5) this value and use it to lookup the record from a database - take into account whatever hashing algorithm you use will produce duplicates. The hash is necessary if you allow URLs over whatever the max column size is in your database for varchar data, assuming you can't search on CLOBs.
Physical File Generation
Physical file generation would create a file that maps to the permanent URL you're imagining. So you'd write something that creates/renames the file at time it's posted. This removes the need for storing a hash and instead you place information about the post you want to serve inside that file (i.e. ID of the post) and pass that along to the front controller.
Recommendation
My preference is the URL rewriting approach, so you don't have to worry about writing dynamic code files out at runtime. That said, if you want something with less magic, or you're expecting a lot of requests, the physical file generation is the way to go because it's more obvious and requires the server to do less work.
i am developing a website where i intend to provide the search feature. I am developing it in PHP/MYSQL and i have written the script to perform the search. I wish to provide autocomplete or suggested searches option in the search box as the user types, can i know what are my choices and how can i make use of them?
I had tried YUI Autocomplete, it looks good to me, however i do not understand when it says using a local proxy for the datasource. Can any one help me out here?
Consider trying the Scriptaculous autocomplete. It's very easy to implement.
what does it exactly say on the documentation? (can you provide a link)
by local proxy I would think it means a proxy to a remote web service or API on another domain. (you can't make requests unless scripts are executed on the same domain). http://developer.yahoo.com/javascript/howto-proxy.html
I used jQuery autocompletex
