  • SetEnvIf regex for setting Content-Disposition HTTP header

    - by Erik Sorensen
    I am attempting to use the IHS 7.0/apache 2.2 SetEnvIf directive to set the filename of a downloaded file based on a url parameter. I think I am pretty close, however if there is a space (encoded or otherwise) in the filename - it fails. example url: http://site.com/path/to/filename.ext/file-title=Nice File Name.ext?file-type=foo apache config: SetEnvIf Request_URI "^.*file-title\=(.*)\??.*$" FILENAME=$1 Header unset "Content-Disposition" Header add "Content-Disposition" "attachment; filename=%{FILENAME}e" UnsetEnv FILENAME An application will specify what is now showing up as "Nice File Title.ext" in the example. This all works great if there are no spaces, however - if there is a space the filename to download will just show up as "Nice". There may or may not be a second set of parameters in the query string (?file-type, etc)

  • MOSS 2007 Pre-Populate SSO Credentials

    - by CaffeineFueled
    I'm looking to set a user's credentials for a particular webpart/application that utilizes the SSO database within Sharepoint. Can someone point me to a code sample of how I might do this in .net? The webpart/application typically stores the user's credentials upon the first use but I'd rather they not even be bothered with entering them at all.

  • nextSibling issue, should be simple

    - by SoLoGHoST
    Ok, I'm trying to come to grips with this nextSibling function in JS. Here's my issue within the following code... var fromRow = document.getElementById("row_1"); while(fromRow.nodeType == 1 && fromRow.nextSibling != null) { var fRowId = fromRow.id; if (!fRowId) continue; // THIS ONLY gets done once and alerts "row_1" ONLY :( alert(fRowId); fromRow = fromRow.nextSibling; } Ok can someone please tell me what is wrong with this code? There are siblings next to this document.getElementById("row_1"); element for sure as I can see them, and they all have id attributes, so why is it not getting the id attributes of the siblings?? I don't get it. row_1 is a TR element, and I need to get the TR elements next to it within this table, but for some reason, it only gets the 1 element that I can already get using document.getElementById, arggg. Thanks guys :)

  • Excel 2007 and Unicode

    - by pjlasl
    I have an israeli spreadsheet reading right to left. When I read the values (using VBA) it places a question mark (?) at the beginning and end of the text, in other words it wraps the text with the question mark (ie ?0123456?). If you type Range("A2").value or .value2 or .text the results are the same. Any idea on how to prevent this?

  • Blackberry apps: Native or webapps?

    - by jpartogi
    Dear all, I have read the Blackberry documentation and it is possible to push a notification from a webapp. I am planning to create a Blackberry application that compliments to our webapps. But I am still left in the middle whether to develop a webapp or native Blackberry app. I have also look at how a webapp runs on Blackberry browser and it looks smooth. From your experience does the native app offer something that the webapp doesn't? Bonus question, is Facebook and Twitter app on Blackberry a native app or a webapp? If it is a webapp, is it possible to make a launcher for the application on Blackberry? Thanks for your help.

  • How to undelete from the SVN Repository

    - by Clay Nichols
    I accidentally deleted a major folder inside of the Tortoise-SVN Repro Browser. The working folder is unaffected. What is the recommended way to reverse that? Do I just Revert back to the previous version? Or do I need to do a Checkout to that previous version into a new folder and delete the old folder?

  • Prevent Text Input expanding in IE

    - by Caroline
    Hi, I am having a problem with an input field in IE. The code is for a portlet and widths need to be dynamic as the user can place the portlet on any of the three columns in the page which all have different widths. As always it works fine in FF but not in IE. In order to make the width dyanaic I have set width="100%". Data to populate the text input comes from a DB. When the page is rendered if there is a long URL the text input expands to fill the contents in IE but in FF it just stays the same width (ie 100% of the TD that it lives in). How can I stop IE from changing the width in order to fit the contents. Setting the width to a fixed width of 100px fixes the issue but I need to have the width as a percentage in order to accommodate the layout of the portlet wherever it is put in on the page. I have tried overflow:hidden and word-wrap:break-word but I cant get either to work. Here is my input code and style sheets <td class="right" > <input type="text" class="validate[custom[url]]" value="" id="linkText" name="communicationLink" maxlength="500" maxsize="100" /> </td> .ofCommunicationsAdmin input { font-family: "Trebuchet MS"; font-size: 11px; font-weight:normal; color:#333333; overflow:hidden; } .ofCommunicationsAdmin #linkText { overflow:hidden; width:100%; border:1px #cccccc solid; background:#F4F7ED top repeat-x; } .ofCommunicationsAdmin td.right { vertical-align: top; text-align: left; }

  • Prevent Session from being created In some cases

    - by Jean Barmash
    In my app, I have an external monitor that pings the app ever few minutes and measures its uptime / response time Every time the monitor connects, a new server session is created, so when I look at the number of sessions, it's always a minimum of 15, even during times where there are no actual users. I tried to address this with putting the session creation code into a filter, but that doesn't seem to do it - I guess session automatically gets created when the user opens the first page? all() { before = { if (actionName=='signin') { def session = request.session //creates session if not exists } } } I can configure the monitor to pass in a paramter if I need to (i.e. http://servername.com/?nosession, but not sure how to make sure the session isn't created.

  • How to write custom (odd) authentication plugins for Wordpress, Joomla and MediaWiki?

    - by Bart van Heukelom
    On our network (a group of related websites - not a LAN) we have a common authentication system which works like this: On a network site ("consumer") the user clicks on a login link This redirects the user to a login page on our auth system ("RAS"). Upon successful login the user is directed back to the consumer site. Extra data is passed in the query string. This extra data does not include any information about the user yet. The consumer site's backend contacts RAS, with this extra data, to get the information about the logged in user (id, name, email, preferences, etc.). So as you can see, the consumer site knows nothing about the authentication method. It doesn't know if it's by username/password, fingerprint, smartcard, or winning a game of poker. This is the main problem I'm encountering when trying to find out how I could write custom authentication plugins for these packages, acting as consumer sites: Wordpress Joomla MediaWiki For example Joomla offers a pretty simple auth plugin system, but it depends on a username/password entered on the Joomla site. Any hints on where to start?
