  • How can you monitor internet download usage?

    - by dv3500ea
    Some broadband providers impose a monthly download limit, charging extra if you go over. It is also quite easy to exceed some of the lower limits just by installing/updating packages and 'normal' browsing (which to me includes streaming TV programs and movies). This means that you need to limit the amount you use the internet, yet it is hard to know when. The System Monitor helps a bit with this by giving a total received/total sent in the networking section of the Resources tab. However, this is reset every reboot. It would be good if there was a way to have a monthly total received so you can know how close you are to exceeding your limit and maybe even be given warnings if it looks like you are going to exceed the limits. Does anyone know of a way to achieve this?

  • 12.04 monitor brightness commands ignored

    - by jarvisschultz
    I cannot change the brightness of the monitor on a laptop either from the command line or from keyboard shortcuts. I have verified that the file in /sys/class/backlight/acpi_video0/brightness is changing. I have also verified that I am running the nvidia drivers. Things I have tried: Adding entries to /etc/default/grub The GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX entries now read GRUB_CMDLINE_LINUX_DEFAULT="quite nosplash acpi_backlight=vendor" GRUB_CMDLINE_LINUX="noapic" I have also tried various commands here (with an update grub and reboot each time) but nothing has helped I enabled brightness control in /etc/X11/xorg.conf so that it now looks like Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Investigated installing linux-kamal-mjgbacklight and determined it was not applicable to my system Nothing seems to have made any difference. I am using an Nvidia GeForce GT 330M with driver version 295.40. Does anyone have any other suggestions?

  • Dual monitor not working after an update

    - by Nimonika
    I did a package manager update yesterday and it turns out that my dual monitor setup has stopped working. I have poor vision so I really need to connect to a much bigger screen, but since yesterday, when I connect the screen to my laptop, the screen does not automatically reset itself to the laptop display. Even after lots of trial and error with the display settings, I am getting different dispalys on the laptop and external screen and right now only the big screen is active while the laptop has blanked out. Please can someone help me setup my dual screens for 11.10 properly. lspci -v | grep -i vga output 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller]

  • Windows move onto second monitor when I turn it on

    - by user1002379
    I'm using a small monitor for my main display I also have an LCD TV hooked up through HDMI as my secondary display. The problem is whenever I turn on the TV most but usually not all of my currently running program windows jump to the secondary display. This is very annoying, because I don't like to keep my TV on unless I'm using it. So when I do turn it on I have to drag and drop each of the windows back on to my main display. I have played around with some Compiz settings to no avail please help.

  • Monitor resolution can't be saved

    - by Iztok
    Today I installed Lubuntu 13.10 on Vmware Player (inside Windows). I change the Monitor setting (resolution) from default 800x600 to 1680x1050. It works. Beside Apply, I also press Save button. "Changes are saved" appears. But - after restart, the resolution is again in 800x600. I also opened /etc/xdg/lxsession/Lubuntu/autostart and add (it was empty before) one line: @xrandr --mode 1680x1050 After restart the default resolution is back again. Any idea?

  • Windows 2008 IIS 7.0 HTTP to HTTPS Redirect -- Versus IIS 6.0 Mechanism

    - by Dan7el
    This topic, creating a mechanism for redirection from HTTP to HTTPS on a Windows 2008 server running IIS 7.0 is a much written-about topic on the Internet. How this is done is really not so much my issue. My issue is more of explaining why this can't be done with the standard HTTP Redirect module that ships with Windows 2008 IIS 7.0. Instead, there are other methods needed that are more arduous. First, the IIS 6.0 method requires no externally available modules nor does it require any additional modifications to the web.config or any type of other development effort. It's outlined here: http://blogs.microsoft.co.il/blogs/dorr/archive/2009/01/13/how-to-force-redirection-from-http-to-https-on-iis-6-0.aspx And, you can see the basic steps are to run the snap-in, get the properties on the site, and do some modifications. Presto, you have the HTTP -- HTTP redirect setup. Now, on the IIS 7.0 platform, it doesn't seem this simple. An initial search found the following site: http://www.sslshopper.com/iis7-redirect-http-to-https.html Which has two separate approcates: 1. Involves installing a separately available Microsoft module -- URL Rewrite Module, and then adding XML to the web.config. 2. Custom Error Page. ...there might be other methods, but these are the basic ones and the first is listed as the primary method. But wait...There exists on the IIS 7.0 an HTTP Redirect Module. So...why can't I use the HTTP Redirect Module to do this very thing? This is really my big question. I need to know this because my management is going to insist I use the HTTP Redirect Module and set up the HTTP to HTTPS redirect in a similar fashion to how we do in IIS 6.0. Can someone please explain to me, in clean, simple, easy to understand, terms that both I and my management can understand as to why I need to go get the URL Rewrite Module and install that on the server and make the web.config changes suggested by the article instead of simply using the HTTP Redirect module that's already installed on the site? Thanks a bunch.

  • Is there a simple LDAP-to-HTTP gateway out there?

    - by larsks
    We have a local LDAP directory that provides basic contact information about our user community. We would like to integrate this into some third-party hosted services that allow us to implement widgets that run arbitrary Javascript. In order to connect Javascript to our LDAP directory, I would like to set up a simple LDAP-to-HTTP proxy that would accept HTTP GET requests, translate them into an appropriate LDAP query, and respond with directory information as JSON-encoded data. In an ideal world, something like this: GET /[email protected] Would get me something like this: { "cn": "Bob Person", "title": "System Administrator", "sn": "Person", "mail": "[email protected]", "telepehoneNumber": "617-555-1212", "givenName": "Bob" } (And this obviously assumes that the web application has locally configured information about what base DN to use, how to authenticate, etc). I guess I could write one...but surely something like this already exists? UPDATE The consensus seems to be that there isn't a pre-existing solution out there and that I should just get off my lazy derriere and write one. So I did, and it's here. It's not especially pretty, but it works for my prototyping and I figure maybe someone else will find it useful someday.

  • Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

    - by ultrasawblade
    I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

  • Referer is passed from HTTPS to HTTP in some cases... How?

    - by ravisorg
    In theory browsers do not pass on referer information from HTTPS to HTTP sites. And in my experience this has always been true. But I just found an exception, and I want to understand why it works so I can use it as well. Search for "what is my referer" on https://www.google.ca/ eg: https://www.google.ca/search?q=what+is+my+referer There are a few sites that will show referer. They all seem to "work" when they shouldn't. For example, click the www.whatismyreferer.com one. I get: Your referer: https://www.google.ca/ Note that sometimes, rarely, I get "no referer" as the result. Go back and click the link again and it'll "work" the next time. This should not happen. www.whatismyreferer.com is a non-HTTPS site. The referer header should not be being passed, but it is. What's going on here, and how can I do the same from my HTTPS site to the HTTP sites I'm linking to?

  • What is the recommended method of HTTP Redirection from multiple URLs to one URL?

    - by ChrisHDog
    I have a website that has a number of URLs that people use to connect to that site (uses the bindings on the IIS website and everything works as intended): http://www.sample.com http://sample.com https://www.sample.com http://xyz.sample.com http://oldurl.com Now what I want to do is have all of the URLs go to https://www.sample.com - so if you type in "http://xyz.sample.com" or "sample.com" you should go to https://www.sample.com The question is what is the best mechanism to do this? I have one possible solution (which I will put as an answer to this question), but I get the feeling that there might be another, better solution available.

  • Errors when connecting to HTTPS using HTTP::Net routines (Ruby on Rails)

    Hi all, the code below explains the problem in detail #this returns error Net::HTTPBadResponse url = URI.parse('https://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this works url = URI.parse('http://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this returns error Net::HTTPBadResponse response = Net::HTTP.post_form(URI.parse('https://sitename.com/remote/register_device'), {:text => 'hello world'}) #this returns error Errno::ECONNRESET (Connection reset by peer) response = Net::HTTP.post_form(URI.parse('https://sandbox.itunes.apple.com/verifyReceipt'), {:text => 'hello world'}) #this works response = Net::HTTP.post_form(URI.parse('http://sitename.com/remote/register_device'), {:text => 'hello world'}) So... how do I send POST parameters to https://sitename.com or https://sandbox.itunes.apple.com/verifyReceipt in this example?

  • Using HTTP status codes to reflect success/failure of Web service request?

    - by jgarbers
    I'm implementing a Web service that returns a JSON-encoded payload. If the service call fails -- say, due to invalid parameters -- a JSON-encoded error is returned. I'm unsure, however, what HTTP status code should be returned in that situation. On one hand, it seems like HTTP status codes are for HTTP: even though an application error is being returned, the HTTP transfer itself was successful, suggesting a 200 OK response. On the other hand, a RESTful approach would seem to suggest that if the caller is attempting to post to a resource, and the JSON parameters of the request are invalid somehow, that a 400 Bad Request is appropriate. I'm using Prototype on the client side, which has a nice mechanism for automatically dispatching to different callbacks based on HTTP status code (onSuccess and onFailure), so I'm tempted to use status codes to indicate service success or failure, but I'd be interested to hear if anyone has opinions or experience with common practice in this matter. Thanks!

  • Building a webserver, client doesn't acknowledge HTTP 200 OK frame.

    - by Evert
    Hi there, I'm building my own webserver based on a tutorial. I have found a simple way to initiate a TCP connection and send one segment of http data (the webserver will run on a microcontroller, so it will be very small) Anyway, the following is the sequence I need to go through: receive SYN send SYN,ACK receive ACK (the connection is now established) receive ACK with HTTP GET command send ACK send FIN,ACK with HTTP data (e.g 200 OK) receive FIN,ACK <- I don't recieve this packet! send ACK Everything works fine until I send my acknowledgement and HTTP 200 OK message. The client won't send an acknowledgement to those two packages and thus no webpage is being displayed. I've added a pcap file of the sequence how I recorded it with wireshark. Pcap file: http://cl.ly/5f5 (now it's the right data) All sequence and acknowledgement numbers are correct, checksum are ok. Flags are also right. I have no idea what is going wrong.

  • Custom http service responds fine to local IP address but NOT to localhost or 127.0.0.1

    - by Scrappydog
    I'm trying to connect to a custom http service written by another developer. The service responds fine on a local IP address and port number. Such as: http://10.1.1.1:1234 but it does NOT respond to http://localhost:1234 or http://127.0.0.1:1234 The service is a simple single function application written in VC++ that takes an http post string and returns another string. I'm trying to all it from C# using HttpWebRequest.GetResponse, but I can reproduce the same problem manually from a web browser... Test environment is Windows 2008 Server. Bottom line I'm looking for some troubleshooting tips to help the other developer fix his code.

  • Setting custom HTTP request headers in an URL object doesn't work.

    - by Blagovest Buyukliev
    I am trying to fetch an image from an IP camera using HTTP. The camera requires HTTP basic authentication, so I have to add the corresponding request header: URL url = new URL("http://myipcam/snapshot.jpg"); URLConnection uc = url.openConnection(); uc.setRequestProperty("Authorization", "Basic " + new String(Base64.encode("user:pass".getBytes()))); // outputs "null" System.out.println(uc.getRequestProperty("Authorization")); I am later passing the url object to ImageIO.read(), and, as you can guess, I am getting an HTTP 401 Unauthorized, although user and pass are correct. What am I doing wrong? I've also tried new URL("http://user:pass@myipcam/snapshot.jpg"), but that doesn't work either.

  • SYS2 Scripts Updated – Scripts to monitor database backup, database space usage and memory grants now available

    - by Davide Mauri
    I’ve just released three new scripts of my “sys2” script collection that can be found on CodePlex: Project Page: http://sys2dmvs.codeplex.com/ Source Code Download: http://sys2dmvs.codeplex.com/SourceControl/changeset/view/57732 The three new scripts are the following sys2.database_backup_info.sql sys2.query_memory_grants.sql sys2.stp_get_databases_space_used_info.sql Here’s some more details: database_backup_info This script has been made to quickly check if and when backup was done. It will report the last full, differential and log backup date and time for each database. Along with these information you’ll also get some additional metadata that shows if a database is a read-only database and its recovery model: By default it will check only the last seven days, but you can change this value just specifying how many days back you want to check. To analyze the last seven days, and list only the database with FULL recovery model without a log backup select * from sys2.databases_backup_info(default) where recovery_model = 3 and log_backup = 0 To analyze the last fifteen days, and list only the database with FULL recovery model with a differential backup select * from sys2.databases_backup_info(15) where recovery_model = 3 and diff_backup = 1 I just love this script, I use it every time I need to check that backups are not too old and that t-log backup are correctly scheduled. query_memory_grants This is just a wrapper around sys.dm_exec_query_memory_grants that enriches the default result set with the text of the query for which memory has been granted or is waiting for a memory grant and, optionally, its execution plan stp_get_databases_space_used_info This is a stored procedure that list all the available databases and for each one the overall size, the used space within that size, the maximum size it may reach and the auto grow options. This is another script I use every day in order to be able to monitor, track and forecast database space usage. As usual feedbacks and suggestions are more than welcome!

  • Web.config WordPress rewrite rules next to Magento

    - by Flo
    I've installed Magento on IIS in folder: E:\mydomain\wwwroot (I already have it all running correctly). I have no deeper folder magento, I placed all files directly in the wwwroot folder, so: wwwroot\app wwwroot\downloader wwwroot\errors wwwroot\includes etc... UPDATE: since I'm on IIS my .htaccess is ignored completely and my web.config rules are used instead. Here's my web.config in folder e:\mydomain\wwwroot: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Magento SEO: remove index.php from URL"> <match url="^(?!index.php)([^?#]*)(\\?([^#]*))?(#(.*))?" /> <conditions> <add input="{URL}" pattern="^/(media|skin|js)/" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:0}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Next, I wanted to install WordPress. I unzipped all files in folder e:\mydomain\wwwroot\wordpress Browsed to www.mydomain.com/wordpress/wp-admin/install.php, where I configured everything for my database. Everything was installed correctly. I then navigate to http://www.mydomain.com/wordpress/wp-login.php where I type my credentials. I seem to be logged in and am redirected to http://www.mydomain.com/wordpress/wp-admin/ But there I receive an empty page. I enabled detailed error message in IIS following this article: http://www.iis.net/learn/troubleshoot/diagnosing-http-errors/how-to-use-http-detailed-errors-in-iis I also checkec with Fiddler and see that I receive a 500 error: GET /wordpress/wp-admin/ HTTP/1.1 Host: www.mydomain.com Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Referer: http://www.mydomain.com/wordpress/wp-login.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,nl;q=0.6 Cookie: wordpress_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7C2d8edb4fc6618f290fadb49b035cad31; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7Cbf822163926b8b8df16d0f1fefb6e02e HTTP/1.1 500 Internal Server Error Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.14 X-Powered-By: ASP.NET Date: Sun, 06 Oct 2013 12:56:03 GMT Content-Length: 0 My WordPress web.config in folder e:\mydomain\wwwroot\wordpress contains: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="wordpress" patternSyntax="Wildcard"> <match url="*"/> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/> </conditions> <action type="Rewrite" url="index.php"/> </rule></rules> </rewrite> </system.webServer> </configuration> I also want my WordPress articles to be available on www.mydomain.com/blog instead of www.mydomain.com/wordpress Ofcourse my admin links for Magento and Wordpress should also work.

  • Write TSQL, win a Kindle.

    - by Fatherjack
    So recently Red Gate launched sqlmonitormetrics.red-gate.com and showed the world how to embed your own scripts harmoniously in a third party tool to get the details that you want about your SQL Server performance. The site has a way to submit your own metrics and take a copy of the ones that other people have submitted to build a library of code to keep track of key metrics of your servers performance. There have been several submissions already but they have now launched a competition to provide an incentive for you to get creative and show us what you can do with a bit of TSQL and the SQL Monitor framework*. What’s it worth? Well, if you are one of the 3 winners then you get to choose either a Kindle Fire or $199. How do you win? Simply write the T-SQL for a SQL Monitor custom metric and the relevant description and introduction for it and submit it via  sqlmonitormetrics.red-gate.com before 14th Sept 2012 and then sit back and wait while the judges review your code and your aims in writing the metric. Who are the judges and how will they judge the metrics? There are two judges for this competition, Steve Jones (Microsoft SQL Server MVP, co-founder of SQLServerCentral.com, author, blogger etc) and Jonathan Allen (um, yeah, Steve has done all the good stuff, I’m here by good fortune). We will be looking to rate the metrics on each of 3 criteria: how the metric can help with performance tuning SQL Server. how having the metric running enables DBA’s to meet best practice. how interesting /original the idea for the metric is. Our combined decision will be final etc etc **  What happens to my metric? Any metrics submitted to the competition will be automatically entered into the site library and become available for sharing once the competition is over. You’ll get full credit for metrics you submit regardless of the competition results. You can enter as many metrics as you like. How long does it take? Honestly? Once you have the T-SQL sorted then so long as you can type your name and your email address you are done : http://sqlmonitormetrics.red-gate.com/share-a-metric/ What can I monitor? If you really really want a Kindle or $199 (and let’s face it, who doesn’t? ) and are momentarily stuck for inspiration, take a look at these example custom metrics that have been written by Stuart Ainsworth, Fabiano Amorim, TJay Belt, Louis Davidson, Grant Fritchey, Brad McGehee and me  to start the library off. There are some great pieces of TSQL in those metrics gathering important stats about how SQL Server is performing.   * – framework may not be the best word here but I was under pressure and couldnt think of a better one. If you prefer try ‘engine’, or ‘application’? I don’t know, pick something that makes sense to you. ** – for the full (legal) version of the rules check the details on sqlmonitormetrics.red-gate.com or send us an email if you want any point clarified. Disclaimer – Jonathan is a Friend of Red Gate and as such, whenever they are discussed, will have a generally positive disposition towards Red Gate tools. Other tools are often available and you should always try others before you come back and buy the Red Gate ones. All code in this blog is provided “as is” and no guarantee, warranty or accuracy is applicable or inferred, run the code on a test server and be sure to understand it before you run it on a server that means a lot to you or your manager.

  • Keeping an Eye on Your Storage

    - by Fatherjack
    There are plenty of resources that advise you about looking for signs that your storage hardware is having problems. SQL Server Alerts for 823, 824 and 825 are covered here by Paul Randall of SQL Skills: http://www.sqlskills.com/blogs/paul/a-little-known-sign-of-impending-doom-error-825/ and here by me: https://www.simple-talk.com/blogs/2011/06/27/alerts-are-good-arent-they/. Now until very recently I wasn’t aware that there was a different way to track the 823 + 824 errors. It was by complete chance that I happened to be searching about in the msdb database when I found the suspect_pages table. Running a query against it I got zero rows. This, as it turns out is a good thing. Highlighting the table name and pressing F1 got me nowhere – Is it just me or does Books Online fail to load properly for no obvious reason sometimes? So I typed the table name into the search bar and got my local version of http://msdn.microsoft.com/en-us/library/ms174425.aspx. From that we get the following description: Contains one row per page that failed with a minor 823 error or an 824 error. Pages are listed in this table because they are suspected of being bad, but they might actually be fine. When a suspect page is repaired, its status is updated in the event_type column. So, in the table we would, on healthy hardware, expect to see zero rows but on disks that are having problems the event_type column would show us what is going on. Where there are suspect pages on the disk the rows would have an event_type value of 1, 2 or 3, where those suspect pages have been restored, repaired or deallocated by DBCC then the value would be 4, 5 or 7. Having this table means that we can set up SQL Monitor to check the status of our hardware as we can create a custom metric based on the query below: USE [msdb] go SELECT COUNT(*) FROM [dbo].[suspect_pages] AS sp All we need to do is set the metric to collect this value and set an alert to email when the value is not 1 and we are then able to let SQL Monitor take care of our storage. Note that the suspect_pages table does not have any updates concerning Error 825 which the links at the top of the page cover in more detail. I would suggest that you set SQL Monitor to alert on the suspect_pages table in addition to other taking other measures to look after your storage hardware and not have it as your only precaution. Microsoft actually pass ownership and administration of the suspect_pages table over to the database administrator (Manage the suspect_pages Table (SQL Server)) and in a surprising move (to me at least) advise DBAs to actively update and archive data in it. The table will only ever contain a maximum of 1000 rows and once full, new rows will not be added. Keeping an eye on this table is pretty important, although In my opinion, if you get to 1000 rows in this table and are not already waiting for new disks to be added to your server you are doing something wrong but if you have 1000 rows in there then you need to move data out quickly because you may be missing some important events on your server.

    - by Jitendra Vyas
    Is bigger size display ( Monitor) always better for Development? I'm going to buy a new LCD Monitor. I mostly work in Adobe Photoshop, HTML, CSS, jQuery and Wordpress. Budget is not a problem. Many options are there for LCD Monitor SIZE My questions are Would it better for maximum size, or large size monitor are not good always? Would it better to buy 21.5 inch x 2 than one 30 inch monitor? Which monitor size would you would prefer between the size of 21.5 inch - 30 inch, if bugdet is not a problem?

  • How to obtain the correct physical size of the monitor?

    - by KindDragon
    How can I get the size of the display in centimeters or inches? This code does not always works correctly: HDC hdc = CreateDC(_T("DISPLAY"),dd.DeviceName,NULL,NULL); int width = GetDeviceCaps(hdc, HORZSIZE); int height = GetDeviceCaps(hdc, VERTSIZE); ReleaseDC(0, hdc) Especially for multi-monitor configuration. Update: I need to get the size just for ordinary monitors, which have a constant physical size.

  • if I set up the expire http header of a css file to 1 year, if I modify that file, will it be ignore

    I'm using rails with nginx/passenger. If I set up the expire http header of a css file to 1 year, if I modify that file, will it be ignored by the browser (ie, it will not request the new version)? Given that Rails adds a different timestamps to each asset such as foo.css?1270165626 every time I restart the server? That's the config I use right now (nginx/passenger): location ~* \.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$ { expires max; break; }
