Problems when CGI environment variables exceed 4KB in size #128

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
If for example PATH environment variable is about 4KB, then Mongoose web server 
will skip adding any further env variables to CGI environment. This includes 
HTTP_ env variables (build from http headers) and phpdesktop env variables 
(temp dir, phpdesktop version etc). The solution is to increase the 
CGI_ENVIRONMENT_SIZE constant in Mongoose web server.

Fixed in revision 615b7caecf84. Limit is now set to 64KB. Also exceeded number 
of env variables to 512.
