Function documentation

THttpServer(const char* engine = "civetweb:8080")
 delete all http engines and sniffer
void SetSniffer(TRootSniffer* sniff)
 Set TRootSniffer to the server
 Server takes ownership over sniffer
Bool_t IsReadOnly() const
 returns read-only mode
void SetReadOnly(Bool_t readonly)
 Set read-only mode for the server (default on)
 In read-only server is not allowed to change any ROOT object, registered to the server
 Server also cannot execute objects method via exe.json request
Bool_t CreateEngine(const char* engine)
 factory method to create different http engines
 At the moment two engine kinds are supported:
  civetweb (default) and fastcgi
   "civetweb:8080" or "http:8080" or ":8080" - creates civetweb web server with http port 8080
   "fastcgi:9000" - creates fastcgi server with port 9000
   "dabc:1237"    - create DABC server with port 1237 (only available with DABC installed)
   "dabc:master_host:port" - attach to DABC master, running on master_host:port (only available with DABC installed)
void SetTimer(Long_t milliSec = 100, Bool_t mode = kTRUE)
 create timer which will invoke ProcessRequests() function periodically
 Timer is required to perform all actions in main ROOT thread
 Method arguments are the same as for TTimer constructor
 By default, sync timer with 100 ms period is created

 If milliSec == 0, no timer will be created.
 In this case application should regularly call ProcessRequests() method.
Bool_t VerifyFilePath(const char* fname)
 Checked that filename does not contains relative path below current directory
 Used to prevent access to files below current directory
Bool_t IsFileRequested(const char* uri, TString& res) const
 Verifies that request is just file name
 File names typically contains prefix like "jsrootsys/"
 If true, method returns real name of the file,
 which should be delivered to the client
 Method is thread safe and can be called from any thread
Bool_t ExecuteHttp(THttpCallArg* arg)
 Executes http request, specified in THttpCallArg structure
 Method can be called from any thread
 Actual execution will be done in main ROOT thread, where analysis code is running.
void ProcessRequests()
 Process requests, submitted for execution
 Regularly invoked by THttpTimer, when somewhere in the code
 gSystem->ProcessEvents() is called.
 User can call serv->ProcessRequests() directly, but only from main analysis thread.
void ProcessRequest(THttpCallArg* arg)
 Process single http request
 Depending from requested path and filename different actions will be performed.
 In most cases information is provided by TRootSniffer class
Bool_t Register(const char* subfolder, TObject* obj)
 Register object in folders hierarchy

 See TRootSniffer::RegisterObject() for more details
Bool_t Unregister(TObject* obj)
 Unregister object in folders hierarchy

 See TRootSniffer::UnregisterObject() for more details
const char * GetMimeType(const char* path)
 Returns MIME type base on file extension
char* ReadFileContent(const char* filename, Int_t& len)
 reads file content
void SetTopName(const char* top)
 these methods used to set http request arguments
const char * GetTopName() const
 returns engine-specific top-name
THttpServer(const char* engine = "civetweb:8080")
TRootSniffer * GetSniffer() const
