• How are Apache HTTP Server and Apache Tomcat related? (If at all)

  - by JW01

  I currently have Apache httpd running on a production Ubuntu VPS server. I write php scripts. I'm interested in learning Java and I was wondering how I would go about writing some server-side Java to work on my current set-up. How are Apache Tomcat and Apache HTTP Server related to each other? Can Tomcat be a module of httpd? Or are they simply just two very different projects that happen to be steered by the same organisation (Apache Software Foundation)?

• Blocking a distributed, consistent spam attack? Could it be something more serious?

  - by mattmcmanus

  I will do my best to try and explain this as it's strange and confusing to me. I posted a little while ago about a sustained spike in mysql queries on a VPS I had recently setup. It turned out to be a single post on a site I was developmenting. The post had over 30,000 spam comments! Since the site was one I was slowly building I hadn't configured the anti-spam comment software yet. I've since deleted the particular post which has given the server a break but the post's url keeps on getting hit. The frustrating thing is every hit is from a different IP. How do I even start to block/prevent this? Is this even something I need to worry about? Here are some more specific details about my setup, just to give some context: Ubuntu 8.10 server with ufw setup The site I'm building is in Drupal which now has Mollom setup for spam control. It wasn't configured before. The requests happen inconsistently. Sometimes it's every couple seconds and other times it's a an or so between hits.

• 301 redirect Rule For Load Balance F5 BigIp

  - by Kshah

  I have a load balancer F5 Big ip for my website. Currently, I am having 302 redirect in place; however, I wanted to apply 301 but dont know how. For example: My website (abc.com) when typed 302 redirects to abc.com/index and when typed www.abc.com 302 redirects www.abc.com/index. I wanted to have a rule which will help me in abc.com - 301 redirect - www.abc.com/index abc.com/index - 301 redirect - www.abc.com/index www.abc.com - 301 redirect - www.abc.com/index Below is the code that my tech person is trying: Redirect to WWW when HTTP_REQUEST { if { [HTTP::host] equals "abc.com" or [HTTP::host] equals "abc.co.in" or [HTTP::host] equals "www.abc.co.in" } { if {!( [HTTP::path] equals "/")} { HTTP::respond 301 Location "http://www.abc.com[HTTP::path]" } } } Redirect POST when HTTP_REQUEST { if { [HTTP::method] equals "POST" } { persist source_addr pool shop_shop_vr4_http } } Redirect-VR4 HOMEPAGE when HTTP_REQUEST { if { [HTTP::path] equals "/" or [HTTP::path] starts_with "/target/" or [HTTP::path] starts_with "/logs/" or [HTTP::path] starts_with "/config/" } { HTTP::redirect "http://[HTTP::host]/index.jsp.vr" } }

• Juju Openstack bundle: Can't launch an instance

  - by user281985

  Deployed bundle:~makyo/openstack/2/openstack, on top of 7 physical boxes and 3 virtual ones. After changing vip_iface strings to point to right devices, e.g., br0 instead of eth0, and defining "/mnt/loopback|30G", in Cinder's block-device string, am able to navigate through openstack dashboard, error free. Following http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/running-an-instance.html instructions, attempted to launch cirros 0.3.1 image; however, novalist shows the instance in

• How to send Content-Disposition headers in apache for files?

  - by Rory McCann

  I have a directory of text files that I'm serving out with apache 2. Normally when I (or any user) access the files they see them in their browser. I want to 'force'* the web browser to pop up a 'Save as' dialog box. I know this is possible to do with the Content-Disposition headers (more info). Is there some way to turn that on for each file? Ideally I'd like something like this: <Directory textfiles> AutoAddContentDispositionHeaders On </Directory> And then apache would set the correct content disposition header, including using the same filename. Something like this might be possible with the apache Header directive. Bonus points if it's included by standing in apache in debian. I could do a simple PHP wrapper script that takes in a filename argument, makes the call to header(...) and then prints the file, but then i have to validdate input etc. that's work I'm trying to avoid. * I know you can't actually force things when it comes to the web

• Two different sites, same IP, same top-level domain, on IIS 7.5 -- one works and the other displays HTTP 404 error

  - by user717236

  I'm running a Windows 2008 R2 box with IIS 7.5 as the web server. On IIS, I have two websites: mysubsite1.mysite.com and mysubsite2.mysite.com. There is only one IP on the server and both sites share this IP. Here is how I have the bindings configured: mysubsite1.mysite.com works fine. However, mysubsite2.mysite.com gives me the following error: Not Found HTTP Error 404. The requested resource is not found. Now, if I change the Host name field for mysubsite1.mysite.com to blank and restart the web server, both sites work! The question is why is the host name field for the first site causing an HTTP 404 error for the second site when both sites' Host name fields are filled? I would appreciate any insight. Thank you.

• URL rewrite from www.domain.com/sudirectory to http://domain.com/subdirectory

  - by chrizzbee

  I need a solution for the following problem: I use a CMS and want the backend only be available at http://domain.com/backend and not at http://www.domain.com/backend. How do I have to change my .htaccess file to achieve this? I already have a rewrite rule from HTTP (non-www) to www. Here's what I currently have in my .htaccess file: ## # Uncomment the following lines to add "www." to the domain: # RewriteCond %{HTTP_HOST} ^shaba-baden\.ch$ [NC] RewriteRule (.*) http://www.shaba-baden.ch/$1 [R=301,L] # # Uncomment the following lines to remove "www." from the domain: # # RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] # RewriteRule (.*) http://example.com/$1 [R=301,L] # # Make sure to replace "example.com" with your domain name. ## So, the first bit is the redirect from HTTP to www. It works on the domain part of the URL. As explained, I need a rewrite rule from the backend login at http://www.shaba-baden.ch/contao to http://shaba-baden.ch/contao

• nginx status code 200 and 304

  I'm using nginx + passenger. I'm trying to understand the nginx response 200 and 304. What does this both means? Sometimes, it responses back in 304 and others only 200. Reading the YUI blog, it seems browser needs the header "Last-Modified" to verify with the server. I'm wondering why the browser need to verify the last modified date. Here is my nginx configuration: location / { root /var/www/placexpert/public; # <--- be sure to point to 'public'! passenger_enabled on; rack_env development; passenger_use_global_queue on; if ($request_filename ~* ^.+\.(jpg|jpeg|gif|png|ico|css|js|swf)$) { expires max; break; } } How would I add the header "Last-Modified" to the static files? Which value should I set?

• Is 301 redirect sufficient to solve WWW and HTTP/S duplication?

  - by Thomas Ojo

  I was reading about this article - SEO preference for WWW or HTTP:// protocol redirection? Do www websites rank better than NON-www? I have same problem but I needed a help on this further. What about https:// How will this be treated? Is the redirect 301 sufficient to solve the problem? I have a SEO company that says if possible, i should not have redirect but I don't think this is visible? Does permanent redirect in any way have effect on SEO services if properly done?

  - by muhammad usman

  I have a fashion website. I had redirected my domain http:// (non-www) to http://www domain and my preferred domain in Google Webmaster Tools was http://www. Now I have redirected http://www to http:// domain and have changed my prefered domain as well. Now Google PageRank is not showing for even a single page.

• How to combine RewriteRule of index.php and queries rewrite and avoid Server Error 404?

  - by Binyamin

  Both RewriteRule's works fine, except when used together. 1.Remove all queries except query ?callback=.*: # /api?callback=foo has no rewrite # /whatever?whatever=foo has 301 redirect /whatever RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^?#\ ]*)\?[^\ ]*\ HTTP/ [NC] RewriteCond %{REQUEST_URI}?%{QUERY_STRING} !/api(/.*)?\?callback=.* RewriteRule .*$ %{REQUEST_URI}? [R=301,L] 2.Rewrite index.php queries api and url=$1: # /api returns data index.php?api&url= # /api/whatever returns data index.php?api&url=whatever RewriteRule ^api(?:/([^/]*))?$ index.php?api&url=$1 [QSA,L] RewriteRule ^([^.]*)$ index.php?url=$1 [QSA,L] Any valid combination to this RewriteRule's on keeping its functionality? This combination will return Server Error 404 to /api/?callback=foo: # Remove all queries except query "callback" RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^?#\ ]*)\?[^\ ]*\ HTTP/ [NC] RewriteCond %{REQUEST_URI}?%{QUERY_STRING} !/api(/.*)?\?callback=.* RewriteRule .*$ %{REQUEST_URI}?

• How to prevent a 404 Error when creating a subdomain and using www to access it?

  - by Chris

  I have installed a multi-site installation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.example.com or http://subdomain.example.com. However when I enter www.subdomain.example.com or http://www.subdomain.example.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

• Weird URLs being access by Googlebot

• Site loads Extremely slowly over HTTPS; loads perfectly over HTTP - Sudden and new issue

  - by guest234239048

  My business' website suddenly started loading extremely slowly over HTTPS last night and continues through today. The facts: Page loadtime via HTTPS - 2 minutes +, HTTP - 3 seconds max. NO updates were done on any site files in the past 2 weeks. This is on Shared Hosting HTTPS has worked perfectly over the past 9 months then suddenly failed yesterday. Hosting company and SSL issuer say there are no problems on their end. - Searches for others having similar issues return no results, it appears to be just me... Site is primarily run via php/mysql Currently attempted troubleshooting: Tried all major browsers and different versions - same result. Tried 2 separate ISPs - same result. Tried proxies - same result. Tried 3 separate computers - same result. I'm basically at a total loss here. Does anyone know what could cause such a thing to happen? Please help guide troubleshooting.

• Spring Security HTTP Basic Authentication

  - by Raspayu

  Hi people! I am trying to do a really simple basic authentication with Spring Security. I have configured properly the namespace, and there are no Exceptions in the server. In my "servlet.xml" I have got the next for Spring Security: <security:http> <security:http-basic></security:http-basic> <security:intercept-url method="POST" pattern="/**" access="ROLE_USER" /> </security:http> <security:authentication-manager alias="authenticationManager"> <security:authentication-provider> <security:user-service> <security:user name="cucu" password="tas" authorities="ROLE_USER" /> <security:user name="bob" password="bobspassword" authorities="ROLE_USER" /> </security:user-service> </security:authentication-provider> </security:authentication-manager> It nearly all goes perfect: the methods that are not POST doesn't prompt any login form, and the POST method prompt it. The problem is, that nor "cucu", neither "bob" can login there. Can anyone see what am I doing wrong? Thanks in advance! ;-)

• How to handle correctly HTTP Digest Authentication on iPhone

  - by Fabiano Francesconi

  Hello guys. I'm trying to upload a file onto my personal server. I've written a small php page that works flawlessy so far. The little weird thing is the fact that I generate all the body of the HTTP message I'm going to send (let's say that amounts to ~4 mb) and then I send the request to my server. The server, then, asks for an HTTP challenge and my delegate connection:didReceiveAuthenticationChallenge:challenge replies to the server with the proper credentials and the data. But, what's happened? The data has been sent twice! In fact I've noticed that when I added the progressbar.. the apps sends the data (4mb), the server asks for authentication, the apps re-sends the data with the authentication (another 4mb). So, at the end, I've sent 8mb. That's wrong. I started googling and searching for a solution but I can't figure out how to fix this. The case scenarios are two (my guess): Share the realm for the whole session (a minimal HTTP request, then challenge, then data) Use the synchronized way to perform an HTTP connection (things that I do not want to do since it seems an ugly way to handle this kind of stuff to me) Thank you

• php: how to return an HTTP 500 code on any error, no matter what

  - by Jake

  Hi guys. I'm writing an authentication script in PHP, to be called as an API, that needs to return 200 only in the case that it approves the request, and 403 (Forbidden) or 500 otherwise. The problem I'm running into is that php returns 200 in the case of error conditions, outputting the error as html instead. How can I make absolutely sure that php will return an HTTP 500 code unless I explicitly return the HTTP 200 or HTTP 403 myself? In other words, I want to turn any and all warning or error conditions into 500s, no exceptions, so that the default case is rejecting the authentication request, and the exception is approving it with a 200 code. I've fiddled with set_error_handler() and error_reporting(), but so far no luck. For example, if the code outputs something before I send the HTTP response code, PHP naturally reports that you can't modify header information after outputting anything. However, this is reported by PHP as a 200 response code with html explaining the problem. I need even this kind of thing to be turned into a 500 code. Is this possible in PHP? Or do I need to do this at a higher level like using mod_rewrite somehow? If that's the case, any idea how I'd set that up? Thanks for any help. Jake

• Reading data from an open HTTP stream

  - by allenjones

  Hi, I am trying to use the .NET WebRequest/WebResponse classes to access the Twitter streaming API here "http://stream.twitter.com/spritzer.json". I need to be able to open the connection and read data incrementally from the open connection. Currently, when I call WebRequest.GetResponse method, it blocks until the entire response is downloaded. I know there is a BeginGetResponse method, but this will just do the same thing on a background thread. I need to get access to the response stream while the download is still happening. This just does not seem possible to me with these classes. There is a specific comment about this in the Twitter documentation: "Please note that some HTTP client libraries only return the response body after the connection has been closed by the server. These clients will not work for accessing the Streaming API. You must use an HTTP client that will return response data incrementally. Most robust HTTP client libraries will provide this functionality. The Apache HttpClient will handle this use case, for example." They point to the Appache HttpClient, but that doesn't help much because I need to use .NET. Any ideas whether this is possible with WebRequest/WebResponse, or do I have to go for lower level networking classes? Maybe there are other libraries that will allow me to do this? Thx Allen
