Architecture :: File Upload To DB Server From Webserver
Dec 2, 2010
I have this scenario. I have an application running in a webserver (in DMZ). End users upload documents to the webserver. right now all the documents get stored in the webserver itself. I would like to store all the docs in the database server.
What is the best way to store the documents, move it from webserver to db server after they uplocaded or directly upload to the db server ?.
And, if I have to upload directly to the db server could someone help me how to mangae the connection to the db server and credentials..?

I have a scenario which I am looking at where large files which are about 30-40 MB are being FTPed to a server. I am looking at creating a .net screen with the FTP control to upload the file to a Unix server. I need to know how much of a performance hit it is to work with such large files, is it a feasible option in this scenario? I might have to create a .net component for the same and call from ASP application. Is it doable?

I have an asp.net application running on a web farm that allows users to upload files and download them later via link to that file. Currently, I use Windows DFS to replicate the local IIS directory where the files are stored across the web farm servers. However, as this solution does not scale out, I want to implement a more scalable solution by partitioning the documents. Specifically, say I set up multiple file storage servers (Fs1, Fs2, Fs3, etc.) on the network. Further, let's say I change my upload page to save the uploaded file to one of the file storage servers on the local LAN (based on some logic). I assume so far I am safe with ASP.NET doing this much assuming I have the correct permission for the ASP.NET process ID. The question I have is withregards to download links. When a user gets served a download link to their document (e.g. http://www.testco.com/data/doc1.txt) is there a way for me to "intercept" that HTTP request and underneath the coversserve the doc1.txt from the file storage server (e.g. Fs2) it resides

I'm planning to make an ASP.NET webserver that provides all kinds of functions, like an API. There will be quite alot functions that can easily be grouped (datasystem, userAccount, fileSystem, and so on). I can make multiple services (asmx files) into a single webserver, and let the clients connect to whatever service(s) they need. However, I'm not sure if it's a wise thing to do... Pack everything into 1 big service(1 asmx file), or split up into many smaller services? How about:
- performance/memory on the server (a client that connets with 1 or 6 services)
- Maximum connections (we will use a Windows XP Server edition computer)
There will be about ~30 computers using it. In a worst case scenario, they each computer could make use of 6 services at the same time, if I decide to split it up. A single client could make use of the fileSystem, account, dataSystem and several other things at the same time.

I am developing a webapplication in ASP.NET 2.0 and MySQL 5.0 Now I want to upload this application to My WebServer (The windows web hosting space which I have purchased).
But I am not much familiar with MySQL, and I Don't Know how can I Upload the database on web server. This database contains approx 14 Tables and 95 Stored procedures. Recently I have developed some small web applications in asp.net with access database, at that time uploading was simple(just upload the access file to App_Data folder) But I don't know how i can do this with MySQL.

I have a question what's the best way to accomplish the following task:
- I have an ASP.NET application with SQL server database (hosted externally at any provider)
- There are a few dedicated client computers anywhere in the world and these client computers shall run a periodic automatic process to upload some data into the database of the webserver. So there is NO user in front of those computers to open a browser and run any kind of upload manually. (These automatic processes are not part of my question, they can be windows services or simply running applications on the desktop.)
My initial idea was to use FTP for this purpose, means: Those perodic processes on the specific clients create files and put these files via FTP in any defined folder of the web server.
But what follows then? Is it possible to have any eternally running process on the web server to process those uploaded files in the FTP folder and write their content into the database? As far as I understood until now an ASP.NET application has sessions and an application process but a session shuts down as soon as the associated client doesn't send a request for some time and even the application process shuts down when no user at all sends a request for a specific time. Isn't it? So in other words: When no user sends any requests via HTTP my application on the webserver is simply not running and therefore cannot process the FTP-uploaded files. (Or can I keep the application "artificially" alive to run a peridic lookup for new files ???)
The other option I had in mind is to program a piece of software running as a windows service which could pick up the FTP-uploaded files and process them. But I have to consider that possibly the hosting company does not allow to install any service programs on their servers aside from the ASP.NET application. So this is probably not a real option.
And now my third idea is to develop an ASP.NET web service which runs on the same web server as the ASP.NET application. The specific clients mentioned above would connect to this web service via HTTP, upload the data and the web service would immediately process the data and write them into the database.
At the moment only the last option seems to be the "most natural" (and perhaps even the only possible ?) way to me. Are there any other options and methods for my purpose? And if so, what is the recommended way?

I need to upload a file (xml, pdf, etc) from the user's PC, but I need to write it directly to a file server. I cannot use FileUpload because there is no way to direct its initial upload to anything but the web server. So, how do I use the HTML INPUT to upload the file from the user's PC directly to a file server located at a different URL than the web server the web page is being hosted on?

I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
