    <p>I was trying to download a pdf file from ieeexplore via PHP, but it seems not working well. Suppose the URL is <a href="http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&amp;arnumber=5534992" rel="nofollow">http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&amp;arnumber=5534992</a>. I wrote the following PHP code:</p> <pre><code>function get_web_page($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_COOKIESESSION, true); curl_setopt($ch, CURLOPT_COOKIEJAR, '/tmp/cookie.txt'); curl_setopt($ch, CURLOPT_COOKIEFILE, '/tmp/cookie.txt'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $page = curl_exec($ch); curl_close($ch); return $page; } </code></pre> <p>But this code failed with nothing downloaded. I checked the received http header in the following:</p> <pre><code>HTTP/1.0 200 Connection established HTTP/1.1 302 Moved Temporarily Server: Sun-ONE-Web-Server/6.1 Date: Mon, 09 Jul 2012 22:11:50 GMT Content-length: 0 Content-type: text/html Set-Cookie: ERIGHTS=na2vLnqZwz9xxRfO2zN8Ny66f0vHi85YE*ynGx2BtGx2FmIHkiEyx2Bg89Db6Qx3Dx3D-18x2dHeJj2k3B7UHsoix2BefrHXeAx3Dx3Dusln2oQUqj3KXiQXjOYx2BMwx3Dx3D-UQmTydx2FMwnGJOyKUw5iVDAx3Dx3D-eV0zE6ztXYKrVZluJrMMbAx3Dx3D;path=/;domain=.ieee.org Location: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&amp;arnumber=5534992&amp;tag=1 Set-Cookie: WLSESSION=874668684.20480.0000; expires=Tue, 10-Jul-2012 22:11:48 GMT; path=/ HTTP/1.1 200 OK Server: Sun-ONE-Web-Server/6.1 Date: Mon, 09 Jul 2012 22:11:50 GMT Content-length: 203 Content-type: text/html; charset=UTF-8 Cache-Control: private Product: 254 Inst: 9690 Licenseowner: 9690 Member: 0 Cache-Control: no-cache Pragma: No-cache Expires: Thu, 01 Jan 1970 00:00:00 GMT Set-Cookie: xploreCookies={"standardsLicenseId":"0","openUrl":"http://linkserv.lib.utk.edu:9003/sfx","enterpriseLicenseId":"0","isIp":"true","desktopReportingUrl":"null","openUrlImgLoc":"http://www.lib.utk.edu/eresources/sfx2.gif","products":"IEL|VDE|","contactName":"NA","isChargebackUser":"false","contactEmail":"NA","oldSessionKey":"na2vLnqZwz9xxRfO2zN8Ny66f0vHi85YE*ynGx2BtGx2FmIHkiEyx2Bg89Db6Qx3Dx3D-18x2dHeJj2k3B7UHsoix2BefrHXeAx3Dx3Dusln2oQUqj3KXiQXjOYx2BMwx3Dx3D-UQmTydx2FMwnGJOyKUw5iVDAx3Dx3D-eV0zE6ztXYKrVZluJrMMbAx3Dx3D","userIds":"9690","instImage":"","isInst":"true","isDelegatedAdmin":"false","isMember":"false","instName":"UNIVERSITY OF TENNESSEE","customerSurvey":"NA","smallBusinessLicenseId":"0","openUrlTxt":"NA"}; domain=.ieee.org; path=/ Set-Cookie: JSESSIONID=V6pLP7XH4nvtQYcvmVc1ry1Y51vDHhkG8SGn9y0LG8XJv3k3hmJs!-1711984930; path=/; HttpOnly X-Powered-By: Servlet/2.5 JSP/2.1 An error has occurred while trying to load your document.

    3. COEven if nothing is downloaded, something is downloaded. There is no right or wrong in HTTP, there is just request and repsonse. So what *exactly* went wrong?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
