  • ASP.NET request queue priority

    - by dan
    I'm on IIS 7 and .NET 4.0. My understanding is that IIS takes requests and passes them off to ASP.NET worker threads. If all the threads are in use, the request goes into a queue and is processed once a thread becomes available. If the queue goes over a certain size, all new requests get a 503 until there is room in the queue again. Is there a way to prioritize the order in which queued requests are served? For example, I have consumer traffic and infrastructure traffic coming to the same server. If there are no available threads, I'd like for the consumer requests to be served first, even if they have arrived after infrastructure requests. Basically I want to replace the request queue with a priority queue. Is this possible with IIS?

  • Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

    - by Tim Mahy
    Hi all, we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

  • Lots of 408 Request Timed Out from same IPs

    - by GreatFire
    Web server: Nginx. Checking our log files, there are many log entries of connections that: take 59-61 seconds send an empty request (or at least none is logged) result in a 408 response (request timed out) do not contain any http_user_agent originate from a limited number of IPs We are monitoring average times to serve responses and this obviously inflates our statistics. Apart from that though, is this a problem? Any idea why it is occurring? Does it suggest that somebody is intentionally messing with us? What should we do?

  • HTTP Range request rejected

    - by Dan
    I am trying to understand why my production environment might be disallowing HTTP RANGE requests. I have a pool of W2K8x64/IIS7 servers behind a pair of Netscaler 9000s. I compose the following request in Fiddler: http://myorigin.example.com/file.flv User-Agent: Fiddler Host: myorigin.example.com Range: bytes=40000-60000 The response looks like: HTTP/1.1 200 OK Cache-Control: public Content-Type: video/x-flv Expires: Thu, 24 Jun 2010 18:23:53 GMT Last-Modified: Sat, 11 Apr 2009 00:16:14 GMT Accept-Ranges: none ETag: f9d5c718-e148-4225-9ca6-d1f91a2a3c08-_633749805744270000 Server: Microsoft-IIS/7.0 Edge-Control: max-age=2592000 X-Powered-By: ASP.NET Date: Tue, 25 May 2010 18:23:53 GMT Content-Length: 443668 "Accept-Ranges: none" tells me that the range request was rejected, but I am not sure where/why as IIS7 accepts Range by default. Could the 'scalers be shooting it down? Thanks, Dan

  • haproxy modify request path

    - by zcourts
    I'm just getting started with HAProxy and I was wondering if its possible to modify the request path for an HTTP request. One of the backend server uses Dropwizard and its assets bundle see here bundle. In my setup /xyz serves static assets /api/xyz serves REST resources With HAProxy I want requests from api.host.com/xyz to be sent to backend/api/xyz and requests from host.com to be sent to backend/ I've gotten most of that working but I can't figure out how to tell HAProxy to change the path, prepending /api/ to anything from api.host.com Is this possible or am I going about this the wrong way?

  • Rewrite request URI based on Host header in HAProxy

    - by DorinC
    I would like to set up HAProxy to forward HTTP requests to some backend servers but I need it to also rewrite the URI part based on the Host. I've read through the doc but it seems that reqirep isn't suitable for this purpose. Any idea if this is even possible with HAProxy? Here are the details of what I'm trying to accomplish: Requests that come in on: http://www.original-domain.com/ would be balanced between: http://server1/domains/www.original-domain.com/ ... http://serverN/domains/www.original-domain.com/ The proxy should be able to handle this for any number of domains (original-domain.com can be anything, it's not limited to a fixed set of values). For this to work HAProxy would need to rewrite a request like this: GET /original-uri HTTP/1.1 Host: original-domain.com to: GET /domains/original-domain.com/original-uri HTTP/1.1 Host: serverN and forward that request to one of the internal servers.

  • Return http status ok (200) on request method OPTIONS Apache

    - by jazz
    I have a apache server which uses Reverse Proxy to connect/direct to a tomcat server. Using virtualHost, RequestHeader set X-Forwarded-Proto "http" ServerName image.abc.local DocumentRoot "/var/www/html" ProxyRequests Off ProxyTimeout 600 ProxyPass /abc http://image.abc.local:9001/abc ProxyPass /xyz http://image.abc.local:9001/xyz ProxyPassReverse /abc http://image.abc.local:9001/abc ProxyPassReverse /xyz http://image.abc.local:9001/xyz what i want to achieve here is that, when there is a REQUEST_METHOD OPTIONS i want simply return HTTP status OK (200). I dont want the request to be received by the tomcat server and process it. For performance based concerns i want this request to be handled at apache level. with all the research i was still unable to get this to run; RewriteEngine on RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule .* - [R=200m] can somebody assist me with what rewrite rule should be there? or is there an alternative to RewriteEngine? Thanks

  • Logging all Firefox HTTP Request Headers?

    - by Hayek
    I'm using Ruby+Watir to request pages through Firefox. I would like to record the headers and content of every http request made through the browser. Would it be possible to configure a proxy solution to store this information, either in a file or pipe it into an application? I'm running Ubuntu x64. // Edit: I would like to store the data in logs because I would like to view it later. Preferably, I am looking for a solution that runs quietly in the background and stores the headers/content in files.

  • IIS6 won't respond to a request for a JS file after accessing through subdomain

    - by James
    I have a site running of www.mysite.com for example. There is a JS file I'm accessing: www.mysite.com/packages.js The first and subsequent times that I acccess that packages.js file causes no problems........until I access a sub-site like this: sub-site.mysite.com This naturally makes a request for that same packages.js....but the site hangs as it just keeps waiting and waiting for that JS file. Going back to the main site, the problem perists there. If I then rename packages.js to say packages2.js it then works in the same way. I can access the file on the main site but after I try and access it through a sub-site IIS then fails to respond to a request for that file. I realise this explanation is a little vague, but has anyone seen this sort of behaviour before? Thanks very much, James.

  • Troubleshooting an NFS server hanging after authenticated mount request

    - by Christoph
    I need some advice on troubleshooting an NFS server problem on Scientific Linux (RHEL) 6.1. The log on the server shows that an authenticated mount request was made: Jan 13 16:30:02 ??? rpc.mountd[3996]: authenticated mount request from ????:784 for /shared-storage/cm/shared (/shared-storage/cm/shared) But after that, it does not continue. On the client, it is also hanging. The interesting thing now is that I have two NFS servers, which should be identical, and the one is working perfectly, but the other exhibits the above mentioned behaviour. The problem is also not completely persistent, i. e. sometimes the mount request succeeds. I assume that the problem must be related to the server rather than to the client, because it is working perfectly on the other server. My question is where I should search the problem. I have already re-created the exports using exportfs -r, I have restarted the NFS server, I have compared the rpcinfo outputs of both server - no success. The problem even survives a reboot. Any other ideas are appreciated. As answer to Tim's question: I have sporadically the following in dmesg, but do not know whether it is related e1000e 0000:0c:00.0: eth4: Detected Hardware Unit Hang: TDH <24> TDT <25> next_to_use <25> next_to_clean <24> buffer_info[next_to_clean]: time_stamp <1c3d12940> next_to_watch <24> jiffies <1c3d12940> next_to_watch.status <0> MAC Status <80383> PHY Status <792d> PHY 1000BASE-T Status <7800> PHY Extended Status <3000> PCI Status <10> Further edit: The problem above does not occur on the machine that is working, so it probably is related. Again an edit: The error is not on the (software) device that is used for NFS, but on another one. The NFS mount also does not trigger the message.

    - by user28317
    I have a Windows 7 and an XP machine connected to a NETGEAR wireless router. Both machines can log into the network and surf the web. Both are connecting wirelessly. I can ping the router from each machine and get a reply. I can ping each machine from the router and get a reply. But i cannot ping each machine from the other; getting a request time out. Subnet IP Addresses are 192.168.1.* Router =1; Win7 = 10; XP = 11; Firewall is currently off in both systems. Since i can ping from router im picking that not the problem anyway. If i try to ping from xp to win7 i get Request Timed Out. If i try to ping from Win7 to Xp i get destination host unreachable. What should i do now? Thanks

  • Send request body data when running siege

    - by qui
    I am trying to use the command line utility Siege to load test a service. The service recieves json in the request body via a POST. I have a file called example-data.json with the json inside. I will eventually turn this into a tiny service which creates random json for testing, but this should do for now I have another file called hit-qa.siege with http://www.qa-url.com POST < example-data.json and i try and run siege -c10 -d1 -r1 -f ops/perf/hammer-dev.siege When I check the logs of the service, it is not recieving anything in the request body. My googles have been fruitless, does anyone know how to accomplish this?

  • Forward Request to Multiple Servers

    - by cactuarz
    We have 2 servers. One is old server and another is the new one. Currently we about doing a migration because the old server is not capable enough to handle everyday requests. The specs are: Old server Ubuntu 10.04 Nginx as Reverse Proxy Apache WSGI Python/Django New Server Ubuntu 10.04 Nginx Gunicorn Python/Django Celery+Redis Our manager asked us to research if the old server can perform multiple forwarding to all incoming request, for example, set Nginx of old server to forward all request to both old and new server. The purpose is to perform unit testing to new server using old server as comparer, see if the new server is ready to take over the role. Please help, if there is an idea, or must install some engine, or what we do is impossible. Many thanks.

  • Request to server x Reply from server y

    - by klaasio
    I need some advice from you guys: I'm dealing with a custom loadbalancer/software for which we will use 2 main servers and about 8 slave servers. In short: User sends request to main server, main server will receive and handle the requests, sends a request to a slave server and slave server should send data DIRECTLY to the "user". User - Main server Main server - Slave server Slave server - User The reason for which data should be send directly to the user and not through the main server is because of bandwidth and low budget. Now I have the following idea's: -IPinIP, but that is not possible in Layer7 (so far i know there some expensive routers for that) -IP Spoof, using C/C++ we will make it look like the reply came from main server. But I was thinking, perhaps the reply "slave server - User" could just come from a different IP without causing issues in the firewall from the user or his anti-virus. I don't know so well about "home" firewalls/routers and/or anti-virus software. I guess the user machine wouldn't handle it well?

  • Browser freeze while ajax call in action

    - by kaivalya
    I have a ASP.NET Web App. I notice that while a simple ajax call(see below) is in process, web application does not respond to any action that I try on a different browser. $.ajax({ type: "GET", async: true, url: "someurl", dataType: "text", cache: false, success: function(msg){ CheckResponse(msg); } }); This happens when I open two firefox or two IE. I run the function that does the ajax call on first browser and till the response of the ajax is returned, I cannot do anything on the second browser on the same site. No breakpoints are hit on the server from the second browser till initial ajax is completed. It hangs for any click etc.. The hang on the second browser ends immediately after the ajax call is completed on the first one. This behavior is not observed if I try the same on IE and Firefox side by side. Only happen with IE & IE or FF & FF side by side Appreciate if you can help me see what I am missing here.

  • asp.net mvc Ajax.BeginForm clone.

    - by denis_n
    Hello, I'm using asp.net mvc ajax. The partial view is using Ajax.BeginForm (just an example): <div id="divPlaceholder"> <% using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "divPlaceholder" })) { %> ... asp.net mvc controls and validation messages <input type="submit" value="Save" /> <% } %> </div> After update, if validation fails, the html is: <div id="divPlaceholder"> <div id="divPlaceholder"> ...form </div> </div> I don't like that the returned html is inserted, instead it should replace original div. Probably on POST I should not render <div> around form in partial view or render the div without id. What else can I do in this situation? I was thinking that maybe I should write a helper, something like Ajax.DivBeginForm, which will render form inside div on GET and hide the div on POST. Can somebody provide a good advice how to write such helper (Ajax.DivBeginForm)? I'd like it to work with using keyword: <% using (Ajax.DivBeginForm(new AjaxOptions { UpdateTargetId = "myId" })) { ... }%>
