  • Crosstab/Cube/Pivot Components for Delphi

    - by Anagoge
    I'm looking for a Delphi VCL crosstab/cube/pivotcube/olap grid component for Delphi 2009, 2010, or XE. I'm willing to sacrifice advanced features to get something open/free (or very cheap if I must) to make it easier to collaborate with any future developers without anyone having to purchase more components than I already use, since this will just be used in one screen. If there isn't anything appropriate out there, I may try to implement something simple on my own. I can live with some fairly basic features: drag and drop to configure dimensions, sort by a column, allow totals/min/max for a column, and (optionally) expand/collapse or drill down to sub-categories. Blazing performance and enterprise scalability are not required, since there should be less than 2000 source rows. There appear to be several decent options in the commercial space (ExpressPivotCube, FastCube, HierCube), but they are all a few hundred dollars. This project already uses existing installations of Excel 2007 and SQL Server 2005/2008, so I might consider leveraging those, though I'd prefer a native Delphi component, if possible. There are also the very old Decision Cube components included in Delphi's Source\xtab directory, but they apparently no longer support unicode compilers (Delphi 2009+), since I got dozens of unicode-related compilation errors while test compiling that source in Delphi XE. Those components also still link to the long-deprecated BDE! Has anyone modified Decision Cube to support unicode/pure-TDataSet? The online tutorials I found were incomplete and silent on the dozens of BDE/unicode compilation errors I see, so I might have to tackle that on my own. Does anyone have suggestions where to start for a free/cheap basic crosstab/pivot grid component?

  • Does Apache need to be stopped to edit "/etc/apache2/sites-available/default"?

    - by webworm
    I am attempting to edit the "default" file located at .. "/etc/apache2/sites-available/default" on my Ubuntu machine running Apache 2.2.8. I want to do this in order to enable the use of .htaccess files. I have downloaded the "default" file and edited it and now I am trying to upload it back to the server via SFTP. I keep getting permission denied errors. Could it be because Apache is running and making use of the file? I am an admin on the machine so I would expect to be able to overwrite the file. Thanks for any assistance.

  • Add HttpOnly flag to cookies on the fly with Apache?

    - by Zack
    So I have a java webapp that uses tomcat with an apache proxy layer. I'm looking to make all cookies set from the app have the httpOnly flag. The problem with this is that tomcat is responsible for setting the flag from the application side and its default (in servlet api 2.5) is false. I was hoping I could set this flag for all cookies on the fly using apache. I've been trying different combinations and the closest I have gotten is setting the last cookie passed to httpOnly which is of course wrong: Header append Set-Cookie "; HttpOnly" I have no way of knowing what cookies/values are going to be passed from the app. Is this even possible?

  • Does Apache allow to authorize an HTTP request based on a result of a subrequest?

    - by Jan Wrobel
    I'm looking for an equivalent of nginx http auth request module but for Apache. For each incoming HTTP requests, the module sends a subrequests to authentication/authorization back-end. Th auth request carries a path and all headers of the original request. Based on the result of the auth request, the original requests is allowed (HTTP code 200), denied (HTTP code 403) or login is requested (HTTP code 401). Such a generic mechanism allows to build really flexible authentication and authorization schemes. Is something like this possible in Apache (likely with a help of some third party module)?

  • How do I password protect IIS in a method analogous to Apache's AuthType / AuthUserFile mechanism?

    - by Matt
    I'm used to doing basic password protection for Apache w/ the following method in Apache config files: AuthType Basic AuthName "By Invitation Only" AuthUserFile /path/to/.htpasswd Require valid-user However, I've been asked to put some protection on a subdirectory of a site running ColdFusion on top of IIS6, and I'm unfamiliar with how to do this. How is this done? What should I look out for? I just need to password protect an administrative subdirectory, so I don't need a full user login system - just something that limits who can access the section of the site.

  • What causes Apache Environment Variable set using mod_rewrite to have "redirect_" appended to name?

    - by trowel
    I am trying to set Apache environment variables (for use in PHP) with the [E=VAR:VAL] flag on RewriteRule rules in an .htaccess file. I have already discovered the variables are accessed in PHP as server variables $_SERVER rather than $_ENV (which makes a certain amount of sense). However, my problem is for some rules the [E=VAR:VAL] flag works as expected and I end up with a variable $_SERVER['VAR'] but for other rules I end with a variable $_SERVER['REDIRECT_VAR'] or $_SERVER['REDIRECT_REDIRECT_VAR'], etc A. What causes an Environment Variable set in Apache using the [E=VAR:VAL] flag to get renamed by having "REDIRECT_" appended to the front of the variable name? B. What can I do to make sure I end up with an Environment Variable with an unchanged name so I can access it in PHP as $SERVER['VAR'] without having to resort to checking for variations of the variable name having one of more instances of "REDIRECT" appended to the front of it?

  • Is it possible to log the first line of the response in apache?

    - by Jeppe Mariager
    Hey, We have an Tomcat server where we're trying to log the HTTP version which the response is sent with. We've seen a few times that it seems to be HTTP/0.9, which kills the content (not supported I guess?). We would like to get some stats on this by using the access log in apache. However, since the header line for this isn't prefixed by anything, we cannot use the %{xxx}o logging. Is there a way to get this? An example: Response is: HTTP/1.1 503 This application is not currently available Server: Apache-Coyote/1.1 Content-Type: text/html;charset=utf-8 Content-Length: 1090 Date: Wed, 12 May 2010 12:53:16 GMT Connection: close And we'd like the catch HTTP/1.1 (alternatively, HTTP/1.1 503 This application is not currently available. Is this possible? We do not have access to the application being served, so we need to do this either as a Java filter, or in the tomcat access log - Preferably in the access log.

  • How to remove 'ApacheMonitor.exe' from notification area

    - by ekaj
    For some reason I had 2 instances of Apache running, and I have no idea how. I also had two instances of ApacheMonitor.exe showing in the "Notification Area Icons" place when you right click on your taskbar and go to properties. To fix the multiple instance issue, I deleted Apache completely and uninstalled the service (I did not use the .msi, I install from a .zip). Anyways, Everything from Apache is gone except the two things in the Notification Area Icon page. Does anyone know how to remove these two icons? I have completely uninstalled Apache, cleaned my registry with CCleaner, and rebooted. Does anyone have any other suggestions? Despite what the picture says, I do NOT have Apache installed, and it is not running.

  • LAMP Stack Location

    - by Artem Moskalev
    I have installed the LAMP stack on Ubuntu 12.04 LTS using the tasksel command. I checked - it works. But I cant find the location of the installaton, I worked with WAMP - there you have a separate folder for Apache, for PHP and for mysql. Now I cant even find where to put the documents I create. Which folder is used to contain my web projects? How to start MySQL console and where to look for its installation directory? Which directories are PHP and Apache installed in? how to erase LAMP stack? I found out that some of the parts of the stack are installed in the root/var and root/etc directories: How can I install the whole LAMP stack in /home?

  • Unable to install Apache 2.2.22 in Ubuntu 12.04

    - by Martin Betz
    I am not able to install Apache 2.2 in Ubuntu 12.04. Here is a snippet from my console log (sorry, it is in German): apache2 : Hängt ab von: apache2-mpm-worker (= 2.2.22-1ubuntu1) soll aber nicht installiert werden oder apache2-mpm-prefork (= 2.2.22-1ubuntu1) aber 2.2.22-1ubuntu1.1 soll installiert werden ... That means like: apache2 depends from apa..worker, but that should not get installed OR from ap...prefork..ubuntu1, but ap...prefork..ubuntu1.1 should get installed. I have no idea how to tackle that issue..

  • Virtual Host under MacOSX not working

    I have setup a virtualhost for MacOSX Apache instalation. This are my steps: edit /private/etc/apache2/httpd.conf removing comment from: Include /private/etc/apache2/extra/httpd-vhosts.conf edit /private/etc/apache2/extra/httpd-vhosts.conf, added: <VirtualHost *:80> ServerName test.local DocumentRoot "/Users/myusername/Sites/Test/public" <Directory "/Users/myusername/Sites/Test/public"> Options Indexes FollowSymLinks Includes AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> edit /private/etc/hosts added 127.0.0.7 test.local Restart Apache But the VirtualHost does not work. To further isolate the problem I check the same configuration with MAMP and the virtual host worked rigth, so the configuration files should be fine. What can be wrong?

  • mod_proxy failing as forward proxy in simple configuration

    - by Stabledog
    (On Mac OS X 10.6, Apache 2.2.11) Following the oft-repeated googled advice, I've set up mod_proxy on my Mac to act as a forward proxy for http requests. My httpd.conf contains this: <IfModule mod_proxy> ProxyRequests On ProxyVia On <Proxy *> Allow from all </Proxy> (Yes, I realize that's not ideal, but I'm behind a firewall trying to figure out why the thing doesn't work at all) So, when I point my browser's proxy settings to the local server (ip_address:80), here's what happens: I browse to http://www.cnn.com I see via sniffer that this is sent to Apache on the Mac Apache responds with its default home page ("It works!" is all this page says) So... Apache is not doing as expected -- it is not forwarding my browser's request out onto the Internet to cnn. Nothing in the logfile indicates an error or problem, and Apache returns a 200 header to the browser. Clearly there is some very basic configuration step I'm not understanding... but what?

  • Apache - create multiple aliases

    - by mc3mcintyre
    I'm trying to setup two websites on my Apache server. One is www.domain.com and the other is test.domain.com. Currently, my 000-default.conf file reads as follows: <VirtualHost www:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. #ServerName www.domain.com #ServerAlias www ServerAdmin [email protected] DocumentRoot /var/www/domain.com/ # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/domain.error.log CustomLog ${APACHE_LOG_DIR}/domain.access.log combined UseCanonicalName on allow from all Options +Indexes # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> <VirtualHost test:80> DocumentRoot "/var/www/domain.com/test/" ServerName test.domain.com ServerAdmin [email protected] ErrorLog ${APACHE_LOG_DIR}/test.domain.error.log CustomLog ${APACHE_LOG_DIR}/test.domain.access.log combined UseCanonicalName on allow from all Options +Indexes </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet As is, when I use a browser to go to the www location, it show me a directory listing. However, if I remove the www:80 on Line 1 and replace it with *:80, it correctly displays the webpage. I don't understand why. Can anyone help me configure this 000-default.conf file so that www goes to "/var/www/domain.com" and that test goes to "/var/www/domain.com/test"? Thank you.

  • htaccess execution order and priority

    - by ChrisRamakers
    Can anyone explain to me in what order apache executes .htaccess files residing in different levels of the same path and how the rewrite rules therein are prioritized? For example, why doesn't the rewrite rule in the first .htaccess below work and is the one in /blog prioritized? .htaccess in / RewriteEngine on RewriteBase / RewriteRule ^blog offline.html [L] .htaccess in /blog RewriteEngine On RewriteBase /blog/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog/index.php [L] Ps: i'm not simply looking for an answer but for a way to understand the apache/modrewrite internals ... why is more important to me than how to fix this :) Thanks!
