HTTP/1.1 RESTFUL JSON Client/Server for mORMot
************************************************
- use internaly the JSON format for content communication
- can be called by TSQLHttpClient class from direct Delphi clients
(see mORMotHttpClient unit)
- can be called by any JSON-aware AJAX application
- can optionaly compress the returned data to optimize Internet bandwidth
- speed is very high: more than 20MB/sec R/W localy on a 1.8GHz Sempron,
i.e. 400Mb/sec of duplex raw IP data, with about 200 <20>s only elapsed
by request (direct call is 50 <20>s, so bottle neck is the Win32 API),
i.e. 5000 requests per second, with 113 result rows (i.e. 4803 bytes
of JSON data each)... try to find a faster JSON HTTP server! ;)
}
interface
{$define COMPRESSSYNLZ}
{ if defined, will use SynLZ for content compression
- SynLZ is much faster than deflate/zip, so is preferred
- can be set global for Client and Server applications
- with SynLZ, the 440 KB JSON for TTestClientServerAccess._TSQLHttpClient
is compressed into 106 KB with no speed penalty (it's even a bit faster)
whereas deflate, even with its level set to 1 (fastest), is 25 % slower
- TSQLHttpClientGeneric.Compression shall contain hcSynLZ to handle it }
{$define COMPRESSDEFLATE}
{ if defined, will use gzip (and not deflate/zip) for content compression
- can be set global for Client and Server applications
- deflate/zip is just broken between browsers and client, and should be
avoided: see http://stackoverflow.com/a/9186091
- SynLZ is faster but only known by Delphi clients: you can enable deflate
when the server is connected an AJAX application (not defined by default)
- if you define both COMPRESSSYNLZ and COMPRESSDEFLATE, the server will use
SynLZ if available, and deflate if not called from a Delphi client
- TSQLHttpClientGeneric.Compression shall contain hcDeflate to handle it }
{.$define USETCPPREFIX}
{ if defined, a prefix will be added to the TCP/IP stream so that it won't be
valid HTTP content any more: it could increase the client/server speed with
some anti-virus software, but the remote access won't work any more with
Internet Browsers nor AJAX applications
- will work only with our THttpServer pure Delphi code, of course
- not defined by default - should be set globally to the project conditionals,
to be defined in both mORMotHttpClient and mORMotHttpServer units }
