IIS + PHP + Page with lots of images = Intermittent 403 errors
- by samJL
I am using an up-to-date Server 2008 R2 Datacenter, running IIS 7.5 and PHP 5.3.6/FastCGI
On PHP pages with lots of images (60+), some of the images fail to load
It is not always the same images-- on each page refresh an image that worked previously may not load, while an image that did not now does
Looking at the Net tab in Firebug reveals that the failing image requests are 403 errors
All of the images are located on the server in question, and the images directory has the correct permissions
I believe this problem is the result of a limit on requests
All of my attempts at researching this problem point to maxConnections setting in IIS, yet mine is set at the highest/default of 4294967295 (maxBandwidth too)
I am also running a ColdFusion site on the same IIS installation, and it does not suffer from 403's on pages with lots of images
I am left thinking that there is another connection limit (in PHP or FastCGI?) overriding the IIS connection limit
I don't see anything that looks like a request limit in the php.ini, what am I missing?
Any help would be appreciated, thank you
