  • Webserver parsing chrome input from post request

    - by ravenspoint
    I am developing a small embedded web server. I want to add parsing of post requests, but I am having a problem with input password fields from Chrome. Firefox and IE work perfectly. The HTML: <form action=start.webem method=post> <input value="START" type=submit /><!--#webem start --> <p>Password: <input TYPE=PASSWORD name=yourname AUTOCOMPLETE=OFF /><br> </form> From Firefox I get POST /stop.webem HTTP/1.1 Host: 127.0.0.1:8080 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100315 Firefox/3.5.9 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:8080/ Content-Type: application/x-www-form-urlencoded Content-Length: 13 yourname=test However from Chrome, about 90% of the time, the yourname=test is missing POST /start.webem HTTP/1.1 Host: 127.0.0.1:8080 Connection: keep-alive User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5 Referer: http://127.0.0.1:8080/ Content-Length: 13 Cache-Control: max-age=0 Origin: http://127.0.0.1:8080 Content-Type: application/x-www-form-urlencoded Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Though, occasionally it does work!!!

  • How can I tell if AUCTeX is available?

    - by Simon Wright
    I have a package which has various features that depend on AUCTeX. As it stands, it requires hand-configuration: (defvar AucTeX-used nil) (if AucTeX-used (progn (require 'tex-site) (require 'latex)) (require 'latex-mode) (setq TeX-command-list nil)) Is there a way to find out whether AUCTeX is available on the machine, to avoid having to set AucTeX-Used by hand? (I'm using GNU Emacs 23.1.1 for Max OS X).

  • Ignore order of elements using xs:extension

    - by Peter Lang
    How can I design my xsd to ignore the sequence of elements? <root> <a/> <b/> </root> <root> <b/> <a/> </root> I need to use extension for code generation reasons, so I tried the following using all: <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://www.example.com/test" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:t="http://www.example.com/test" > <xs:complexType name="BaseType"> <xs:all> <xs:element name="a" type="xs:string" /> </xs:all> </xs:complexType> <xs:complexType name="ExtendedType"> <xs:complexContent> <xs:extension base="t:BaseType"> <xs:all> <!-- ERROR --> <xs:element name="b" type="xs:string" /> </xs:all> </xs:extension> </xs:complexContent> </xs:complexType> <xs:element name="root" type="t:ExtendedType"></xs:element> </xs:schema> This xsd is not valid though, the following error is reported at <!-- ERROR -->: cos-all-limited.1.2: An all model group must appear in a particle with {min occurs} = {max occurs} = 1, and that particle must be part of a pair which constitutes the {content type} of a complex type definition. Documentation of cos-all-limited.1.2 says: 1.2 the {term} property of a particle with {max occurs}=1 which is part of a pair which constitutes the {content type} of a complex type definition. I don't really understand this (neither xsd nor English native speaker :) ). Am I doing the wrong thing, am I doing the right thing wrong, or is there no way to achieve this? Thanks!

  • UTF-8 GET using Indy 10.5.8.0 and Delphi XE2

    - by Bogdan Botezatu
    I'm writing my first Unicode application with Delphi XE2 and I've stumbled upon an issue with GET requests to an Unicode URL. Shortly put, it's a routine in a MP3 tagging application that takes a track title and an artist and queries Last.FM for the corresponding album, track no and genre. I have the following code: function GetMP3Info(artist, track: string) : TMP3Data //<---(This is a record) var TrackTitle, ArtistTitle : WideString; webquery : WideString; [....] WebQuery := UTF8Encode('http://ws.audioscrobbler.com/2.0/?method=track.getcorrection&api_key=' + apikey + '&artist=' + artist + '&track=' + track); //[processing the result in the web query, getting the correction for the artist and title] // eg: for artist := Bucovina and track := Mestecanis, the corrected values are //ArtistTitle := Bucovina; // TrackTitle := Mestecani?; //Now here is the tricky part: webquery := UTF8Encode('http://ws.audioscrobbler.com/2.0/?method=track.getInfo&api_key=' + apikey + '&artist=' + unescape(ArtistTitle) + '&track=' + unescape(TrackTitle)); //the unescape function replaces spaces (' ') with '+' to comply with the last.fm requests [some more processing] end; The webquery looks in a TMemo just right (http://ws.audioscrobbler.com/2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestecani?) Yet, when I try to send a GET() to the webquery using IdHTTP (with the ContentEncoding property set to 'UTF-8'), I see in Wireshark that the component is GET-ing the data to the ANSI value '/2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestec?ni?' Here is the full headers for the GET requests and responses: GET /2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestec?ni? HTTP/1.1 Content-Encoding: UTF-8 Host: ws.audioscrobbler.com Accept: text/html, */* Accept-Encoding: identity User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.23) Gecko/20110920 Firefox/3.6.23 SearchToolbar/1.22011-10-16 20:20:07 HTTP/1.0 400 Bad Request Date: Tue, 09 Oct 2012 20:46:31 GMT Server: Apache/2.2.22 (Unix) X-Web-Node: www204 Access-Control-Allow-Origin: * Access-Control-Allow-Methods: POST, GET, OPTIONS Access-Control-Max-Age: 86400 Cache-Control: max-age=10 Expires: Tue, 09 Oct 2012 20:46:42 GMT Content-Length: 114 Connection: close Content-Type: text/xml; charset=utf-8; <?xml version="1.0" encoding="utf-8"?> <lfm status="failed"> <error code="6"> Track not found </error> </lfm> The question that puzzles me is am I overseeing anything related to setting the property of the tidhttp control? How can I stop the well-formated URL i'm composing in the application from getting wrongfully sent to the server? Thanks.

  • How many copies of files are needed by video server?

    - by Trilok
    A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?

  • Python sock.listen(...)

    - by Ian
    All the examples I've seen of sock.listen(5) in the python documentation suggest I should set the max backlog number to be 5. This is causing a problem for my app since I'm expecting some very high volume (many concurrent connections). I set it to 200 and haven't seen any problems on my system, but was wondering how high I can set it before it causes problems.. Anyone know?

  • How do BitTorrents connect with eachother?

    - by mazzzzz
    Hey guys, I was just downloading a new distro of linux using uTorrent, and started to wonder how uTorrent (and other bittorrents) send files to eachother through NAT routers? They obviously use the trackers to get introduced, but how do they pass info to eachother? Is there a whitepaper on this? I couldn't find one :/ Thanks, Max

  • Is derived table executed once or three times?

    - by AspOnMyNet
    Every time you make use of a derived table, that query is going to be executed. When using a CTE, that result set is pulled back once and only once within a single query. Does the quote suggest that the following query will cause derived table to be executed three times ( once for each aggregate function’s call ): SELECT AVG(OrdersPlaced),MAX(OrdersPlaced),MIN(OrdersPlaced) FROM ( SELECT v.VendorID, v.[Name] AS VendorName, COUNT(*) AS OrdersPlaced FROM Purchasing.PurchaseOrderHeader AS poh INNER JOIN Purchasing.Vendor AS v ON poh.VendorID = v.VendorID GROUP BY v.VendorID, v.[Name] ) AS x thanx

  • (resolved) empty response body in ajax (or 206 Partial Content)

    - by Nikita Rybak
    Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

I understand this is a common newbie problem when reading XML, still not able to solve what I am doing wrong, probably something with the Namespace "val" ?
