curl_exec outputs content with php 5.2

[adube]

Issue

While setuping geoprisma on the new linux server which has php 5.2, I noticed that the curl_exec() calls sometimes outputs the response, thus resulting in having unwanted text at the beginning of the page.

Solution

Setting CURLOPT_RETURNTRANSFER to 1 and use the response from curl_exec() instead of using ob_get_contents().

Fixed in r1283.
