  • Application specific mapping in FastCGI ISAPI 1.5

    No Comments

    IIS team recently released FastCGI ISAPI 1.5 for IIS 5.1 and IIS 6.0. One of the major new features added in this release is per application process pools. Per application process pools allow users to specify a unique FastCGI mapping for a particular web application in fcgiext.ini. Using this functionality administrators can now choose to run a web application with PHP version which can be different from what is used for rest of the PHP applications in the same site or the server. This was always possible in IIS 7.0 and 7.5 by overriding PHP handler in web.config but not on WinXP and Win2K3. Version 1.0 of FastCGI ISAPI only allowed specifying a different process pool at a site level granularity. Read more ...

  • Inconsistencies in wincache statistics page explained

    1 Comment

    Many customers running WinCache reported seeing different cache statistics on consecutive requests to wincache.php. Specifically, cache uptime and opcode cache summary returned second time by wincache.php was completely different than the data returned first time. Occasionally data shown in the opcode cache summary table didn’t match the chart displayed on its side. Many customers correctly guessed that this happens because there are multiple cache instances present in different php-cgi processes but thought that none of the PHP processes are sharing cache data and were worried about excessive memory usage by WinCache. I have been replying to many customers personally and posting on forums explaining why they see this behavior but as more and more customers are using WinCache, this question is becoming more common.

  • Feature additions and bug fixes coming up in WinCache

    No Comments

    We are seeing huge momentum behind adoption of WinCache. In the month of September, WinCache v1 Beta was downloaded more than 13,000 times making it one of the most downloaded IIS extensions in the first month following its release. Many happy customers chose to run it on their production servers despite its beta tag. We got very encouraging feedback from the beta release and we are pushing hard for our next release. Our next release date is approaching fast and I wanted to give an update on new features and bug fixes. If your favorite feature was missing in the beta and is also not in the list below, please email me or post on the forums so that we can consider it for future releases of WinCache. Read more ...

  • Migrating FastCGI configuration from IIS 5.1/6.0 to IIS 7.0/7.5

    1 Comment

    Problem
    As you know FastCGI functionality on IIS 5.1 and IIS 6.0 is provided by FastCGI ISAPI extension which is available as an independent download. On IIS 7.0 and beyond, FastCGI functionality is provided by IIS FastCGI module which comes with the operating system. These components use different configuration stores to store the settings that affect their behavior. FastCGI ISAPI uses an INI file named fcgiext.ini as its configuration store whereas FastCGI module keeps configuration in applicationHost.config in xml format with rest of IIS configuration. Before, migrating from IIS6 to IIS7 involved migrating fcgiext.ini configuration to FastCGI module manually as there was no automated way to do that. MSDeploy only had functionality to migrate metabase configuration but because FastCGI ISAPI configuration is kept separately in an INI file, that wasn’t possible. Read more ...

  • Improvements to FastCGI in IIS 7.5

    3 Comments

    Following improvements have been made to FastCGI module in Win7 (and Win2K8 R2).

    1.       Monitor changes to a file

    We have added ability to monitor changes to a file for each FastCGI process pool. Module will recycle FastCGI processes for the process pool if a change to the file is detected. Users can specify file path to monitor using system.webServer/fastCgi/application@monitorChangesTo property. Value can be absolute path to the file or path relative to the folder containing FastCGI executable. In case of php, if fullPath property is set to “c:\php\php-cgi.exe”, monitorChangesTo property can be set to “php.ini” or “c:\php\php.ini”. If file to monitor is not found, status code 500 is returned on each request. Default value of this property is blank which means no file monitoring. Read more ...
