• Cannot connect to Github?

  - by user2973438

  so I tried to push some updates onto my repo on github via terminal on Mac OSX 10.8.4 and it doesn't work. I've been getting the same error many times: Lillys-MacBook-Air:Yuewei Lilly$ git push origin master error: Failed connect to github.com:443; Operation timed out while accessing https://github.com/lillybeans/Yuewei.git/info/refs?service=git-receive-pack fatal: HTTP request failed Some background: I've pushed many projects onto github before using terminal (when I was in Canada). I am currently in Shanghai, China, could it be the GFW? But when I was in Beijing, I was able to push projects onto github still. when I do ping github.com: Lillys-MacBook-Air:Yuewei Lilly$ ping github.com PING github.com (192.30.252.131): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 ping: sendto: No route to host Request timeout for icmp_seq 2 ping: sendto: Host is down Request timeout for icmp_seq 3 ping: sendto: Host is down Request timeout for icmp_seq 4 ping: sendto: Host is down Request timeout for icmp_seq 5 ping: sendto: Host is down Request timeout for icmp_seq 6 ping: sendto: Host is down Request timeout for icmp_seq 7 ^C --- github.com ping statistics --- 9 packets transmitted, 0 packets received, 100.0% packet loss Lillys-MacBook-Air:Yuewei Lilly$ I have ShadowSocks (proxy) turned on. Without it I can't access github.com via browser, with it, I can. also when I do "git remote -v" I see both my pull and push remote repos correctly listed. Thank you in advance!

• Socket select() Handling Abrupt Disconnections

  - by Genesis

  I am currently trying to fix a bug in a proxy server I have written relating to the socket select() call. I am using the Poco C++ libraries (using SocketReactor) and the issue is actually in the Poco code which may be a bug but I have yet to receive any confirmation of this from them. What is happening is whenever a connection abruptly terminates the socket select() call is returning immediately which is what I believe it is meant to do? Anyway, it returns all of the disconnected sockets within the readable set of file descriptors but the problem is that an exception "Socket is not connected" is thrown when Poco tries to fire the onReadable event handler which is where I would be putting the code to deal with this. Given that the exception is silently caught and the onReadable event is never fired, the select() call keeps returning immediately resulting in an infinite loop in the SocketReactor. I was considering modifying the Poco code so that rather than catching the exception silently it fires a new event called onDisconnected or something like that so that a cleanup can be performed. My question is, are there any elegant ways of determining whether a socket has closed abnormally using select() calls? I was thinking of using the exception message to determine when this has occured but this seems dirty to me.

• Sencha 2 : Sync models with hasMany associations in LocalStorage

  - by Alytrem

  After hours and hours trying to do this, I need your help. I have to models : Project and Task. A project hasMany tasks and a task belong to a project. Everyting works well if you don't use a store to save these models. I want to save both tasks and projects in two stores (TaskStore and ProjectStore). These stores use a LocalStorage proxy. I tried many things, and the most logical is : Ext.define('MyApp.model.Task', { extend: 'Ext.data.Model', config: { fields: [ { name: 'name', type: 'string' }, { dateFormat: 'd/m/Y g:i', name: 'start', type: 'date' }, { dateFormat: 'd/m/Y g:i', name: 'end', type: 'date' }, { name: 'status', type: 'string' } ], belongsTo: { model: 'MyApp.model.Project' } } }); Ext.define('MyApp.model.Project', { extend: 'Ext.data.Model', alias: 'model.Project', config: { hasMany: { associationKey: 'tasks', model: 'MyApp.model.Task', autoLoad: true, foreignKey: 'project_id', name: 'tasks', store: {storeId: "TaskStore"} }, fields: [ { name: 'name', type: 'string' }, { dateFormat: 'd/m/Y', name: 'start', type: 'date' }, { dateFormat: 'd/m/Y', name: 'end', type: 'date' } ] } }); This is my "main" : var project = Ext.create("MyApp.model.Project", {name: "mojo", start: "17/03/2011", end: "17/03/2012", status: "termine"}); var task = Ext.create("MyApp.model.Task", {name: "todo", start: "17/03/2011 10:00", end: "17/03/2012 19:00", status: "termine"}); project.tasks().add(task); Ext.getStore("ProjectStore").add(project); The project is added to the store, but task is not. Why ?!

• Updating a field in a record dyanamically in extjs

  - by Daemon

  Scenario I want to update the column data of particular record in grid having store with static data. Here is my store: : : extend : 'Ext.data.Store', model : 'MyModel', autoLoad:true, proxy: { type: 'ajax', url:'app/data/data.json', reader: { type: 'json', root: 'users' } }, My data.json { 'users': [ { QMgrStatus:"active", QMgrName: 'R01QN00_LQYV', ChannelStatus:'active', ChannelName : 'LQYV.L.CLNT', MxConn: 50 } ] } What I am doing to update the record : var grid = Ext.getCmp('MyGrid'); var store = Ext.getStore('Mystore'); store.each(function(record,idx){ val = record.get('ChannelName'); if(val == "LQYV.L.CLNT"){ record.set('ChannelStatus','inactive'); record.commit(); } }); console.log(store); grid.getView().refresh(); MY PROBLEM I am getting the record updated over here.It is not getting reflected in my grid panel.The grid is using the same old store(static).Is the problem of static data? Or am I missing something or going somewhere wrong? Please help me out with this issue.Thanks a lot. MY EDIT I am tryng to color code the column based on the status.But here I am always getting the status="active" even though I am updating the store. What I am trying to do in my grid { xtype : 'grid', itemId : 'InterfaceQueueGrid', id :'MyGrid', store : 'Mytore', height : 216, width : 600, columns : [ { text: 'QueueMgr Status', dataIndex: 'QMgrStatus' , width:80 }, { text: 'Queue Manager \n Name', dataIndex: 'QMgrName' , width: 138}, { text: 'Channel Status',dataIndex: 'ChannelStatus' , width: 78,align:'center', renderer: function(value, meta, record) { var val = record.get('ChannelStatus'); console.log(val); // Here I am always getting status="active". if (val == 'inactive') { return '<img src="redIcon.png"/>'; }else if (val == 'active') { return '<img src="greenIcon.png"/>'; } } }, { text: 'Channel Name', align:'center', dataIndex: 'ChannelName', width: 80} { text: 'Max Connections', align:'center', dataIndex: 'MxConn', width: 80} ] }

• How do I see if an established socket is stuck on a server that's expecting input?

  - by Parker

  I have a script that scans ports for open proxy servers. Problem is if it encounters a login program (specifically telnet) then it hangs there forever since it doesn't know what to do and eventually the server closes the connection. The simple solution would be to create a bunch of cases. If telnet, do this. If SSH, do that. If something else, blah blah blah. I'd like an umbrella solution since the script is not a high priority for me. The script, as it is now, is available at http://parkrrr.net/socks/scan.phps On a small scale (the page maybe averages 15 hits/day) it's fine but on a larger scale I'd be worried about a lot of open zombie sockets. Swapping the !$strpos doesn't work since servers can return more information than what you requested (headers, ads, etc). Only accepting a fixed number of bytes (as opposed to appending until EOF, which it does now) from the $fgets also does not seem to work. I am sure this is where it gets stuck: while (!feof($fp)) { $data.=fgets($fp,512); } But what can I do? Any other suggestions/warnings would also be welcomed.

• FDs not closed in FUSE filesystem

  - by cor

  Hi, I have a problem while implementing a fuse filesystem in python. for now i just have a proxy filesystem, exactly like a mount --bind would be. But, any file created, opened, or read on my filesystem is not released (the corresponding FD is not closed) Here is an example : yume% ./ProxyFs.py `pwd`/test yume% cd test yume% ls mdr yume% echo test test yume% ls mdr test yume% ps auxwww | grep python cor 22822 0.0 0.0 43596 4696 ?

• Spinner setonitemselectedlistener is not called

  - by Gabrielle

  I have a strange problem. I need to do something when an item from spinner is selected. Here is my code : language = (Spinner) findViewById(R.id.current_language_text); ArrayAdapter adapter = new ArrayAdapter(this, com.Orange.R.layout.my_spinner_textview, languages); adapter.setDropDownViewResource(com.Orange.R.layout.multiline_spinner_dropdown_item); language.setAdapter(adapter); language.setSelection(Integer.valueOf(language_id) - 1); language.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { System.out.println("position "+position); Toast.makeText(Settings.this, "Hello Toast",Toast.LENGTH_SHORT).show(); } @Override public void onNothingSelected(AdapterView<?> parentView) { // your code here } }); The problem is that onItemSelectedListener is not called. I put System.out.println in onItemSelected() but I don't get it in LogCat. I tried with Toast, and I get the same, it doesn't appear. Every time I select an item from spinner, in LogCat I get this warning : Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@2b1dabd0 Any idea why onItemSelectedListener is not called ?

• Using groovy ws with enum types?

  - by Jared

  I'm trying to use groovy ws to call a webservice. One of the properties of the generated class is it's self a class with an enum type. Although the debug messages show that the com.test.FinalActionType is created at runtime when the WSDL is read I can't create an instance of it using code like proxy.create("com.test.FinalActionType") When I try and assign a string to my class uin place of an instance of FinalActionType groovy is not able to do the conversion. How can I get an instance of this class to use in a webservice call? I've pasted the important part of the WSDL below. <xsd:simpleType name="FinalActionType"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="stop"/> <xsd:enumeration value="quit"/> <xsd:enumeration value="continue"/> <xsd:whiteSpace value="collapse"/> </xsd:restriction> </xsd:simpleType>

• C++ private inheritance and static members/types

  - by WearyMonkey

  I am trying to stop a class from being able to convert its 'this' pointer into a pointer of one of its interfaces. I do this by using private inheritance via a middle proxy class. The problem is that I find private inheritance makes all public static members and types of the base class inaccessible to all classes under the inheriting class in the hierarchy. class Base { public: enum Enum { value }; }; class Middle : private Base { }; class Child : public Middle { public: void Method() { Base::Enum e = Base::value; // doesn't compile BAD! Base* base = this; // doesn't compile GOOD! } }; I've tried this in both VS2008 (the required version) and VS2010, neither work. Can anyone think of a workaround? Or a different approach to stopping the conversion? Also I am curios of the behavior, is it just a side effect of the compiler implementation, or is it by design? If by design, then why? I always thought of private inheritance to mean that nobody knows Middle inherits from Base. However, the exhibited behavior implies private inheritance means a lot more than that, in-fact Child has less access to Base than any namespace not in the class hierarchy!

• How to replace auto-implemented c# get body at runtime or compile time?

  - by qstarin

  I've been trying to figure this out all night, but I guess my knowledge of the .Net Framework just isn't that deep and the problem doesn't exactly Google well, but if I can get a nod in the right direction I'm sure I can implement it, one way or another. I'd like to be able to declare a property decorated with a custom attribute as such: public MyClass { [ReplaceWithExpressionFrom(typeof(SomeOtherClass))] public virtual bool MyProperty { get; } } public SomeOtherClass : IExpressionHolder<MyClass, bool> { ... } public interface IExpressionHolder<TArg, TResult> { Expression<Func<TArg, TResult>> Expression { get; } } And then somehow - this is the part I'm having trouble figuring - replace the automatically generated implementation of that getter with a piece of custom code, something like: Type expressionHolderType = LookupAttributeCtorArgTypeInDeclarationOfPropertyWereReplacing(); return ReplaceWithExpressionFromAttribute.GetCompiledExpressionFrom(expressionHolderType)(this); The main thing I'm not sure how to do is replace the automatic implementation of the get. The first thing that came to mind was PostSharp, but that's a more complicated dependency than I care for. I'd much prefer a way to code it without using post-processing attached to the build (I think that's the jist of how PostSharp sinks its hooks in anyway). The other part of this I'm not so sure about is how to retrieve the type parameter passed to the particular instantiation of the ReplaceWithExpressionFrom attribute (where it decorates the property whose body I want to replace; in other words, how do I get typeof(SomeOtherClass) where I'm coding the get body replacement). I plan to cache compiled expressions from concrete instances of IExpressionHolder, as I don't want to do that every time the property gets retrieved. I figure this has just got to be possible. At the very least I figure I should be able to search an assembly for any method decorated with the attribute and somehow proxy the class or just replace the IL or .. something? And I'd like to make the integration as smooth as possible, so if this can be done without explicitly calling a registration or initialization method somewhere that'd be super great. Thanks!

• jQuery/Ajax IE7 - Long requests fail

  - by iQ

  Hi guys, I have a problem with IE7 regarding an ajax call that is made by jQuery.load function. Basically the request works in cases where the URL string is not too long, but as soon as the URL gets very large it fails. Doing some debugging on the Ajax call I found this error: URL: <blanked out security reasons but it's very long> Content Type: Headers size (bytes): 0 Data size (bytes): 0 Total size (bytes): 0 Transferred data size (bytes): 0 Cached data: No Error result: 0x800c0005 Error constant: INET_E_RESOURCE_NOT_FOUND Error description: The server or proxy was not found Extended error result: 0x7a Extended error description: The data area passed to a system call is too small. As you can see, it looks like nothing is being sent. Now this only happens on IE7 but not other browsers, with IE8 there is a small delay but still works. The same request works fine when the URL string is relatively small. Now I need this working on IE7 for compatibility reasons and I cannot find workarounds for this so any help is greatly appreciated. The actual ajax call is like this: $("ID").load("url?lotsofparams",callbac func(){}); "lotsofparams" can vary, sometimes being small or very large. It's when the string is very large that I get the above error for IE7 only.

• How do I retrieve twitter xml for Flash site via php properly

  - by daidai

  Am I using TwitterScript to retrieve Twitter data for inside a Flash site. Due to Twitter's crossdomain policy, I need to setup a php proxy... Firstly I made a simple one <?php $url = $_GET['url']; readfile($url); ?> but I then get this error URL file-access is disabled in the server configuration which is only resolved by getting my host to turn fopen() on, which I don't want to do. Then I found this <?php function get_content($url) { $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_HEADER, 0); ob_start(); curl_exec ($ch); curl_close ($ch); $string = ob_get_contents(); ob_end_clean(); return $string; } #usage: $url = $_GET['url']; $content = get_content ($url); var_dump ($content); ?> which solves that problem but the data now is the correct XML but looks like: string(39950) "<?xml version="1.0" encoding="UTF-8"?> <statuses type="array"> <status> ... </statuses>" How do I get the XML data out of that string?

• Selective replication with CouchDB

  - by FRotthowe

  I'm currently evaluating possible solutions to the follwing problem: A set of data entries must be synchonized between multiple clients, where each client may only view (or even know about the existence of) a subset of the data. Each client "owns" some of the elements, and the decision who else can read or modify those elements may only be made by the owner. To complicate this situation even more, each element (and each element revision) must have an unique identifier that is equal for all clients. While the latter sounds like a perfect task for CouchDB (and a document based data model would fit my needs perfectly), I'm not sure if the authentication/authorization subsystem of CouchDB can handle these requirements: While it should be possible to restict write access using validation functions, there doesn't seem to be a way to authorize read access. All solutions I've found for this problem propose to route all CouchDB requests through a proxy (or an application layer) that handles authorization. So, the question is: Is it possible to implement an authorization layer that filters requests to the database so that access is granted only to documents that the requesting client has read access to and still use the replication mechanism of CouchDB? Simplified, this would be some kind of "selective replication" where only some of the documents, and not the whole database is replicated. I would also be thankful for directions to some detailed information about how replication works. The CouchDB wiki and even the "Definite Guide" Book are not too specific about that.

• Synfony2 validation changes invalid integer to 0

  - by Craig

  I've added validation to a form and found that in some cases it is losing the invalid data I am feeding it and saving 0s instead. The output at the bottom shows that if I post the latitude as 'zzzzzz' (clearly not a number nor between -90 and 90) the form is declared as valid and saved with the value 0 How can that happen given that I have declared the input must be a number? ProxyType.php buildForm() $builder ->add('siteName', null, array('label' => 'Site name')) .... ->add('latitude', 'number', array('label' => 'Latitude')) ->add('longitude', 'number', array('label' => 'Longitude')) .... ; ProxyController.php createAction .... $postData = $request->request->get('niwa_pictbundle_proxytype'); $this->get('logger')->info('Posted latitude = '.$postData['latitude']); $form = $this->createForm(new ProxyType(), $entity); $form->bindRequest($request); if ($form->isValid()) { $this->get('logger')->info('Form declared valid : latlong ('.$entity->getLatitude().','.$entity->getLongitude().')'); .... validation.yml Acme\PictBundle\Entity\Proxy: properties: longitude: - Min: { limit: -180 } - Max: { limit: 180 } latitude: - Max: { limit: 90 } - Min: { limit: -90 } Output [2012-09-28 02:05:30] app.INFO: Posted latitude = zzzzzz [] [] [2012-09-28 02:05:30] app.INFO: Form declared valid : latlong (0,0) [] []

• Session scoped bean as class attribute of Spring MVC Controller

  - by Sotirios Delimanolis

  I have a User class: @Component @Scope("session") public class User { private String username; } And a Controller class: @Controller public class UserManager { @Autowired private User user; @ModelAttribute("user") private User createUser() { return user; } @RequestMapping(value = "/user") public String getUser(HttpServletRequest request) { Random r = new Random(); user.setUsername(new Double(r.nextDouble()).toString()); request.getSession().invalidate(); request.getSession(true); return "user"; } } I invalidate the session so that the next time i got to /users, I get another user. I'm expecting a different user because of user's session scope, but I get the same user. I checked in debug mode and it is the same object id in memory. My bean is declared as so: <bean id="user" class="org.synchronica.domain.User"> <aop:scoped-proxy/> </bean> I'm new to spring, so I'm obviously doing something wrong. I want one instance of User for each session. How?

• Reading PDF form field data from Flex 4 ( via php or coldfusion )

  - by Brian Russel Davis

  Been searching web for an answer for this for a MONTH. I am not an expert in Coldfusion. So supposedly this is easy in CF -- but the mark-up confuses the HECK out of me. So here I am. I have managed to import and read a PDF using the CF Proxy for Actionscript: http://forums.adobe.com/thread/754629?tstart=0 --- BUT --- After all my trouble there, the precious form filed information that I was looking for was not there in the PDF info object. GRRRR. So I am back to looking for a way to do this with CFC's or CFM's or PHP. All I want is this: Read the PDF from a Flex app. GET the form field information. WRITE a new PDF with the form field values. I have found so many close but no cigar options ... and I have tried so many that failed. There are so many free PDF this and that out there. But Adobe seems to reserve the real functionality for themselves. All the free options don't seem to have access to the form data? Anyways I am so exhausted with looking for ways to do this. I need help!

• Framework/service for hosting and managing files

  - by Peteris Caune

  Hi, in a webapp I'm building there is a planned side feature of supporting product illustrations and manuals (so pictures and PDFs), possibly arranged in galleries. As I'd rather not implement from scratch all of the uploading, managing and serving of this content, I'm looking for existing solutions which I could integrate. For example, I'm considering Flickr--users of webapp specify their Flickr username and then use some naming convention to link objects in my webapp with pictures uploaded in their Flickr account. Very little code to write from my side, maybe just some API calls that proxy Flickr APIs, since Flickr would handle picture uploading, organizing them in sets, storing them in cloud and serving them in various sizes etc. One drawback here is that either all of the the pictures are public or I have to deal with interactive Flickr authorization. Also not sure if Flickr would be happy being used in such manner. What other online services or libraries/frameworks I should look at? My webapp is written in Python/Pylons, so Python libraries would be preferred. I'm already using some of Amazon infrastructure, so frontends to Amazon S3 would be cool. For online services, RESTful API would be nice.

• Designers, Expression or SharePoint Designer, and real source control

  - by David Lively

  I'm trying desperately to move from VSS to a real source control system. Options include TFS and SVN. My designers need to keep their ability to modify source files and instantly preview their changes in a browser without having to commit their changes. Using FPSE with VSS, this works flawlessly, since saving a file causes the copy in the working folder on the dev server to be updated, so they can just save and refresh their browser which is pointed at the dev server. The site in question consists of 350k+ lines of classic ASP code and some new ASP.NET MVC. They only need to be able to modify views within the MVC code, not C#. Though Expression includes a version of Cassini for local debugging, Cassini does not support classic ASP. Surely someone has solved this problem before. It can't be necessary to install IIS on each designer's machine (this is absolutely untenable). I need a way to have a common working folder on a dev webserver updated whenever someone saves a file locally, just like using FPSE. I'd rather not write an FPSE proxy that knows how to talk to TFS/SVN. Any suggestions? (I know I've asked this question in the past, but I haven't yet found a solution.)

• How can I programmatically get the connection status of OSX network services?

  - by BigBrainz

  In the OS X System Preferences, when I click on 'Network' I see a green dot by 'Ethernet', and red dots by 'AirPort' and 'FireWire'. This is because I turned off AirPort and FireWire, as I access networks and the Internet via Ethernet. I need to programmatically determine which of these network services displayed in System Preferences have green dots and which have red dots. For Ethernet and FireWire the displayed status is 'Connected' or 'Not Connected', and for AirPort the displayed status is 'On' or 'Off'. Perhaps other network services have other status labels. I have picked through all the plist files in '/Library/Preferences/SystemConfiguration', particularly 'preferences.plist' and 'NetworkInterfaces.plist'. I can get all sorts of information there, such as the Location set, network service order, proxy information (which is also important to my task), but I cannot find how to determine whether a given network service is on or off--the equivalent of having the green dot displayed. I have also tried using System Configuration framework, specifically the SCNetworkConnectionGetStatus function, but all I get are invalid connection statuses. Does anyone know how to actually retrieve this connection status information? Thanks.

• In Maven 2, Is it possible to specify a mirror for everything, but allow for failover to direct repo

  - by Justin Searls

  I understand that part of the appeal of setting up a Maven mirror, such as the following: <mirror> <id>nexus</id> <name>Maven Repository</name> <mirrorOf>*</mirrorOf> <url>http://server:8081/nexus/content/groups/public</url> </mirror> ... is that the documentation states, "You can force Maven to use a single repository by having it mirror all repository requests." However, is this also an indication that by having a * mirror set up each workstation [b]must[/b] be forced to go through the mirror? I ask because I would like each workstation to failover and connect directly to whatever public repositories it knows about in the event that Nexus can't resolve a dependency or plugin. (In a perfect world, each developer has the access necessary to add additional proxy repositories as needed. However, sometimes that access isn't available; sometimes the Nexus server goes down; sometimes it suffers a Java heap error.) Is this "mirror but go ahead and connect directly to public repos" failover configuration possible in Maven 2? Will it be in Maven 3?

• How to use JOIN using Hibernate's session.createSQLQuery()

  - by javauser71

  Hi All, I have two Entity (tables) - Employee & Project. An Employee can have multiple Projects. Project table's CREATOR_ID field refers to Employee table's ID field. Employee entity maintains a list of Project. Using EntityManager following query works fine - "entityManager.createQuery("select e from EmployeeDTO e, ProjectDTO p where p.id = ?1 and p.creator.id=e.id"); But since I have the LAZY association relationship, I get error: "Could not initialize proxy - no Session" if I try to access Project info from Employee entity. This is expected and so I am using Hibernate's Session to create query as shown below. Session session = HibernateUtil.getSessionFactory().openSession(); org.hibernate.Query q = session.createSQLQuery("SELECT E FROM EMPLOYEE_TAB E, PROJECT_TAB P WHERE P.ID = " + projectId + " AND P.CREATOR_ID = E.ID") .addEntity("EmployeeDTO ", EmployeeDTO.class) .addEntity("ProjectDTO", ProjectDTO.class); But I get error like: "Column 'E' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification..." Can anyone suggest what will be the right JOIN syntax for such case? If I use ("SELECT * FROM EMPLOYEE_TAB E, ........") - it gives other error: "java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.im.server.dto.EmployeeDTO". Thanks in advance.

• Authentication system - Return information that have to change every time

  - by paulohr

  I have a application (made in Delphi) that contains a Authentication system (login & password). This system is in PHP, and the application get results from PHP using HTTP GET method. The system returns 'OK' if login and password are correct, and 'NO' if not correct. Like this... procedure Check; var x: string; begin x:=Get('www.mywebsite.com/auth.php?user=xxxxxx&pass=zzzzzz'); if x='OK' then UnlockFeatures else MessageBox(0,'You're not VIP','Error',0); end; Well, it works fine, but it is very easy to circumvent this system with sniffers, packet editor or proxy. So, I want to get some information (in PHP) that changes every time, and that could be possible get the same information by my application. What can I do? I don't need codes. Just tips, suggestions, please... Thanks...

• Apache, Nginx, WSGI, django cookies get lost.

  - by Jack M.

  I'm running into a problem trying to get a Django application running in my staging environment. I'm running nginx as a reverse proxy with Apache 2.2/mod_wsgi as the target, and my Django app behind that. The problem is that the cookies are getting lost somewhere between nginx and Apache. My nginx.conf (ripped out a few locations to keep it small): http { gzip on; 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_pass_header Set-Cookie; upstream django { server 127.0.0.1:8080; } server { listen 80; server_name encendio.iigins.com; location / { proxy_pass http://django; } } } My Apache vhosts file: <VirtualHost *:8080> ServerName encendio.test.com ServerAdmin [email protected] DocumentRoot "/usr/local/www/apache22/data" WSGIScriptAlias / /usr/local/www/apache22/data/sasquatch/wsgi_handler.py </VirtualHost> If I directly to http://encendio.test.com:8080/ the cookies work and I can log into the admin area. If I log into http://encendio.test.com/, the admin area tells me my browser isn't using cookies. Now things get kind of weird. I went so far as to look at the environ being passed into my wsgi_handler.py: _application = django.core.handlers.wsgi.WSGIHandler() def application(environ, start_response): print >> sys.stderr, environ.get('HTTP_COOKIE', "No Cookie") return _application(environ, start_response) It shows the cookie existing in the environment: [Mon Mar 22 12:15:50 2010] [error] csrftoken=9f2569elkj67984242f0e7a6dea0b791; sessionid=4e5432hjkds8603f26d5ffa02b10cd27 And this cookie matches up with what I see in nginx's log if I plug in $http_cookie on the end of the log. So Apache is getting the cookie in some form, but it's not ending up where Django can see it. I'm at my wit's end for why this isn't working, so any help is greatly appreciated. Ninja Edit: I forgot to mention that Firefox is seeing the cookies. The oddity is that every time I attempt to log in, I get a new sessionid.
