  • Do you know how to move the Team Foundation Server cache

    - by Martin Hinshelwood
    There are a number of reasons why you may want to change the folder that you store the TFS Cache. It can take up “some” amount of room so moving it to another drive can be beneficial. This is the source control Cache that TFS uses to cache data from the database. Moving the Cache is pretty easy and should allow you to organise your server space a little more efficiently. You may also get a performance improvement (although small) by putting it on another drive.. Create a new directory to store the Cache. e.g. “d:\TfsCache\” Figure: Create a new folder Give the local TFS WPG group full control of the directory   Figure: You need to use the App Tier Service WPG In the application tier web.config (~\Application Tier\Web Services\web.config) add the following setting (to the appSettings section). Figure: The web.config for TFS is stored in the application folder <appsettings> ... <add value="D:\" key="dataDirectory" /> ... </appsettings> Figure: Adding this to the web.config will trigger a restart of the app pool Figure: Your web.config should look something like this The app pool will automatically recycle and Team Web Access will start using the new location.  If you then download a file (not via a proxy) a folder with a GUID should be created immediately in the folder from #1.  If the folder doesn’t appear, then you probably don’t have permissions set up properly.

  • Using The Windows Server AppFabric Cache with ASP.NET

    Did you know that you can use the AppFabric Cache with ASP.NET?  AppFabric Cache provides an ASP.NET session state provider.  There are a number of reasons that you would want to consider using the AppFabric Cache instead of other caching technologies, including the built in ASP.NET caching. The AppFabric Cache provides a number of benefits to ASP.NET programmers.  When web applications need to maintain state, especially across a Web Farm, or needs to maintain objects across restarts...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • delete /var/cache/* How can I fix it?

    - by user110474
    I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back. I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically? If not, which directories do I have to create in /var/cache/ manually to let everything work fine? I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there. I hope somebody can guide me to fix this issue.

  • Remove home page from Google cache

    - by Steve
    The Google Webmaster Tools Remove URL section allows you to specify a page URL to be removed from the index, or cache, or both. However, I want to remove just the home page, which is / I want to remove it from the cache because it is indexed when the "under construction" page was up. This URL is not recognised by the Remove URL section as an individual page. Instead Google assumes you want to remove the entire website from the index. I've specified /index.php and /index.html to be removed from the cache, but this is not the URL listed in the search results for the home page I want removed from the cache.

  • Send/cache multidimensional array to php with jQuery

    - by robertdd
    hy, i have a little, big problem here :) after i upload some images i get a list with all the images. I have some jQuery function for rotate, duplicate, delete, shuffle images! when i select a image and hit delete i send a post to php with the alt="" value of the image,i identify the picture and edit. I want to make a save button, Instead of sending a post every time i rotate a image, better send a post after editing the list of images with an array that contains all data? my php array after upload looks like this: [files] => Array ( [lcxkijgr] => lcxkijgr.jpg [xcewxpfv] => xcewxpfv.jpg [rtiurwxf] => rtiurwxf.jpg [gsbxdsdc] => gsbxdsdc.jpg ) say that I uploaded 4 pictures, firs picture i rotate 90 degrees second i want to duplicate third i rotate 270 degrees and the fourth image i delete i can do all this only with jQuery, but on the server the images are the same, after a refresh the images are the same this is the list with the images: <div class="upimage"> <ul id="upimagesQueue"> <li id="upimagesHPVEJM"> <a href="javascript:jQuery('#upimagesHPVEJM').showlargeimage('HPVEJM')"> <img alt="lcxkijgr" src="uploads/s6id9r9icnp8q9102h8md9kfd7/lcxkijgr.jpg?1272087830477" id="HPVEJM" style="display: block;" > </a> </li> <li id="upimagesSTCSAV"> <a href="javascript:jQuery('#upimagesSTCSAV').showlargeimage('STCSAV')"> <img alt="xcewxpfv" src="uploads/s6id9r9icnp8q9102h8md9kfd7/xcewxpfv.jpg?1272087831360" id="STCSAV" style="display: block;" > </a> </li> <li id="upimagesBFPUEQ"> <a href="javascript:jQuery('#upimagesBFPUEQ').showlargeimage('BFPUEQ')"> <img alt="rtiurwxf" src="uploads/s6id9r9icnp8q9102h8md9kfd7/rtiurwxf.jpg?1272087832162" id="BFPUEQ" style="display: block;" > </a> </li> <li id="upimagesRKXNSV"> <a href="javascript:jQuery('#upimagesRKXNSV').showlargeimage('RKXNSV')"> <img alt="gsbxdsdc" src="uploads/s6id9r9icnp8q9102h8md9kfd7/gsbxdsdc.jpg?1272087832957" id="RKXNSV" style="display: block;"> </a> </li> <ul> </div> is ok if i make one array like this: array{ imgFromLi = array(img1,img2,img3,img4,img5,img6) rotate = array{img1=90, img2=270, img3=90} delete = array{img4,img5,img6} duplicate = array{img2, img3} } how i can send/cache this array?? sorry for my very bad english

  • How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

    - by Continuation
    Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?

  • How can I keep a file in Windows 7's cache?

    - by netvope
    Sometimes you know better than Windows what files will be re-used later. Suppose you have 8GB of memory, and you use the same 1GB file every hour in an I/O-bound application (which takes 1 second to finish if the file is cached, and 1 minute if not.) Now you process some other 16GB of data that are not going to be re-used. Naturally the frequently used 1GB file will be pushed out of the cache. It would be beneficial if one can tell Windows to keep that 1GB file in memory. (Better yet, it would be great if I can tell Windows not to cache those 16GB of data, but I'm not optimistic that this can be done.) The poor-man's way to keep a file in the cache would be to keep reading the file. Are there any better ways? Are you aware of any programs that do this? (If this can be easily done under Linux, please let me know too.)

  • How to invalidate nginx reverse proxy cache in front of other nginx servers?

    - by Olivier Lance
    I'm running a Proxmox server on a single IP address, that will dispatch HTTP requests to containers depending on the requested host. I am using nginx on the Proxmox side to listen to HTTP requests and I am using the proxy_pass directive in my different server blocks to dispatch requests according to the server_name. My containers run on Ubuntu and are also running a nginx instance. I'm having troubles with caching on a particular website that is fully static: nginx keeps on serving me stale content after files updates, until I: Clear /var/cache/nginx/ and restart nginx or set proxy_cache off for this server and reload the config Here's the detail of my configuration: On the server (proxmox): /etc/nginx/nginx.conf: user www-data; worker_processes 8; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; tcp_nodelay on; #keepalive_timeout 65; types_hash_max_size 2048; server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; client_body_buffer_size 1k; client_max_body_size 8m; large_client_header_buffers 1 1K; ignore_invalid_headers on; client_body_timeout 5; client_header_timeout 5; keepalive_timeout 5 5; send_timeout 5; server_name_in_redirect off; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_vary on; gzip_proxied any; gzip_comp_level 6; # gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; limit_conn_zone $binary_remote_addr zone=gulag:1m; limit_conn gulag 50; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/conf.d/proxy.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_hide_header X-Powered-By; proxy_intercept_errors on; proxy_buffering on; proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:10m inactive=7d max_size=700m; /etc/nginx/sites-available/my-domain.conf: server { listen 80; server_name .my-domain.com; access_log off; location / { proxy_pass http://my-domain.local:80/; proxy_cache cache; proxy_cache_valid 12h; expires 30d; proxy_cache_use_stale error timeout invalid_header updating; } } On the container (my-domain.local): nginx.conf: (everything is inside the main config file -- it's been done quickly...) user www-data; worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip off; server { listen 80; server_name .my-domain.com; root /var/www; access_log logs/host.access.log; } } I've read many blog posts and answers before resolving to posting my own questions... most answers I can see suggest setting sendfile off; but that didn't work for me. I have tried many other things, double checked my settings and all seems fine. So I'm wondering whether I am not expecting nginx's cache to do something it's not meant to...? Basically, I thought that if one of my static files in my container was updated, the cache in my reverse proxy would be invalidated and my browser would get the new version of the file when it requests it... But I now have the sentiment I misunderstood many things. Of all things, I now wonder how nginx on the server can know about a file in the container has changed? I have seen a directive proxy_header_pass (or something alike), should I use this to let the nginx instance from the container somehow inform the one in Proxmox about updated files? Is this expectation just a dream, or can I do it with nginx on my current architecture?

  • How to make sure clients update their browser cache when my website is updated?

    - by user64204
    I am using the HTTP 1.1 Cache-Control header to implement client-side caching. Since I update my website only once a month I would like the CSS and JS files to be cached for 30 days with Cache-Control: max-age=2592000. The problem is that the 30-day period defined by Cache-Control doesn't coincide with the website update cycle, it starts from the moment the users visit the site and ends 30 days later, which means an update could occur in the meantime and users would be running with outdated content for a while, which could break the rendering of the website if for instance the HTML and CSS no longer match. How can I perform client-side caching of content for periods of several days but somehow get users to refresh their CSS/JS files after the website has been updated? One solution I could think of is that if website updates can be schedule, the max-age returned by the server could be decreased every day accordingly so that no matter when people visit the website, the end of caching period would coincide with the update of the website, but changing the server configuration every day goes against one of my sysadmin principles (once it's running, don't touch it).

  • Apache Cache with multiple CacheRoots

    - by Tobias Greitzke
    I configured Apache with a CacheRoot directory for each of my domains / virtual hosts: <VirtualHost> ServerName domain1.tld ... CacheRoot /var/www/vhosts/domain1.tld/httpdocs/cache ... </VirtualHost> <VirtualHost> ServerName domain2.tld ... CacheRoot /var/www/vhosts/domain2.tld/httpdocs/cache ... </VirtualHost> I have this up and running for quite a while and so fare it's working pretty well except that I have to empty out the cache manually every so often because htcacheclean does't know of the different directories. Now I would like to setup htcacheclean to watch over the cache directories but as fare as I understand the manual, I can only set it to one cache directory. I would like to do something like this but that doesn't work: <VirtualHost> ServerName domain1.tld ... CacheRoot /var/www/vhosts/domain1.tld/httpdocs/cache htcacheclean -n -t -p/var/www/vhosts/domain1.tld/httpdocs/cache -l1024M ... </VirtualHost> Is it even right to have multiple cache directorys or should I work with just one cache directory for all of the domains?

  • Linux - How to control Winbind Authentication cache timeout

    - by cybervedaa
    I have configured my linux machines (running CentOS 5.2) to authenticate against a Windows server running Active Directory. I have even enabled winbind offline logon. Everything works as expected, however I'm also looking to impose a TTL for the winbind authentication cache. So far all I found was the below snippet from the samba documentation winbind cache time (G) This parameter specifies the number of seconds the winbindd(8) daemon will cache user and group information before querying a Windows NT server again. **This does not apply to authentication requests**, these are always evaluated in real time unless the winbind offline logon option has been enabled. Default: winbind cache time = 300 Clearly the winbind cache time parameter does not control the cache TTL for authentication requests. Is there any other way I can implement a cache timeout for winbind authentication requests? Thank you

  • How to download media content on demand and reuse from browser cache in silverlight

    - by Andrew
    Hi. I have a problem with simple silverlight app, this app has a couple of buttons, each button sets mediaelement source to a short mp3 file and plays it, my problem is that when i press the same button second time it re-downloads mp3 file again but i think it shouldn't, instead it should use a copy of browser cached mp3 file that was downloaded when a button was pressed for the first time. I'm using sl4 and links in mediaelement are just simple uri's, i need to make it working in this way that when some mp3 was downloaded it will be cached on the client browser and further click on button will use a cached version of file instead of downloading it again and wasting my bandwidth. Any ideas ?

  • Best way to cache resized images using PHP and MySQL

    - by Chris Hawes
    What would be the best practice way to handle the caching of images using PHP. The filename is currently stored in a MySQL database which is renamed to a GUID on upload, along with the original filename and alt tag. When the image is put into the HTML pages it is done so using a url such as '/images/get/200x200/{guid}.jpg which is rewritten to a php script. This allows my designers to specify (roughly - the source image maybe smaller) the file size. The php script then creates a hash of the size (200x200 in the url) and the GUID filename and if the file has been generated before (file with the name of the hash exists in TMP directory) sends the file from the application TMP directory. If the hashed filename does not exist, then it is created, written to disk and served up in the same manner, Is this efficient as it could be? (It also supports watermarking the images and the watermarking settings are stored in the hash as well, but thats out of scope for this.)

  • Accessing ruby counter cache

    - by Julian
    Hi all, I'm playing around with a fork of acts_as_taggable_on_steroids as a learning exercise. The version I'm looking at does some stuff I don't understand to calculate Tag counts. So I thought I'd do a version using PORC (Plain Old Rails Counters): class Tagging < ActiveRecord::Base #:nodoc: belongs_to :tag, :counter_cache => "tagging_counter_cache" ... I thought tagging_counter_cache was transparently accessed when I access tag.taggings.count but apparently not? Do I really have to access tag.tagging_counter_cache explicitly? >> tag.taggings.count SQL (0.7ms) SELECT count(*) AS count_all FROM `taggings` WHERE (`taggings`.tag_id = 16) Same for size. It's cool if that's the case but just wanted to check.

  • Gravatar server cache

    Does anyone know how and when Gravatar refreshes their icon caches? I changed my gravatar image for an email about a week ago. For the most part, my profiles that use it have had their avatar icons of various sizes refreshed, except one. In particular, the following URIs, while using the exact same email hash, fetch two completely different images: http://www.gravatar.com/avatar/73166d43fc3b2dc5f56669ce27984ad0?d=identicon&s=35 http://www.gravatar.com/avatar/73166d43fc3b2dc5f56669ce27984ad0?s=35&d=identicon

  • How do I use the subversion revision of a css file to prevent browser cache

    - by Clayton
    StackOverflow implements it like this: <link rel="stylesheet" href="http://sstatic.net/so/all.css?v=4542"> Every time the referenced files change, the href attribute of the link tag is updated in the HTML code, thus supporting caching and updated referenced files. My question - how do you retrieve the subversion version of that css file to include in the link? Subversion keywords only tell you the revision of the file you are currently in. I'm working with PHP/CodeIgniter + jQuery.

  • How to implement a Counter Cache in Rails?

    - by yuval
    I have a posts controller and a comments controller. Post has many comments, and comments belong to Post. The associate is set up with the counter_cache option turned on as such: #Inside post.rb has_many :comments #Inside comment.rb belongs_to :post, :counter_cache => true I have a comments_count column in my posts table that is defaulted to zero, as such: add_column :posts, :comments_count, :integer, :default => 0 In the create action of my comments controller, I have the following code: def create @posts = Post.find(params[:post_id]) @comment = @post.comments.build(params[:comment]) if @comment.save redirect_to root else render :action => 'new' end end My problem: when @comment.save is called, I get the following error: ArgumentError in CommentsController#create wrong number of arguments (2 for 0) Removing :counter_cache => true from comment.rb completely solves the problem, so I'm assuming that it is the cause of this vague error. What am I missing here? How can I save my comment and still have rails take care of my counter_cache for my post? Thanks!
